Why Solar Home System Quality Standard is Important?

In the end-selling market, people always see the same configuration products with alike appearance but have a huge price gap. Also, this situation happens when solar products distributors purchase devices from manufacturers—they don’t know why the same figure on the datasheet but the quotations are totally different until they sell the sleazy items and receive so lots of customer complaints.

The truth is that the costs of solar home systems or solar lanterns are comparatively high, and most consumers simply cannot afford to purchase something that does not meet expectations or is prone to early breakage, which was the reason that impedes households replacing kerosene with modern clean electricity.

Solar Run Apollo Solar Home System

For protecting consumers from low-quality products and for enhancing consumer confidence, Lighting Global (Now called Verasol Standard) developed a series of Quality Standards and testing methods for pico-PV lanterns and solar home systems.

In order to meet Lighting Global Standards, products are tested against a baseline level of quality, durability, and truth-in-advertising. Products must also carry a warranty. These standards have ensured the product quality from the production chain to after-sale service.

Shenzhen Solar Run Energy (Solar Run) is a company that keeps following the latest quality standard in the industry and until now it owns 13 products that meet Lighting Global Standard (Now called Verasol). As a Chinese company, Solar Run is aware of the importance of enhancing market confidence because most materials and products are shipped from China, thus Solar Run must take responsibility and work with international organizations to build the highest standard.

Lighting Global Verification for Solar Home System

The reason why Solar Run follows Lighting Global’s step is also that their test methods have been adopted by the International Electrotechnical Commission (IEC) as a reference point for quality assurance of off-grid lighting products (IEC Technical Specification 62257-9-5), and also the updated standard by Verasol IEC 62257-9-8.

Through the adoption of world level standards and many kinds of accompanying measures, national governments in Africa are helping to boost the availability of high-quality off-grid solar lighting and energy products – and at an affordable price for consumers.

Furthermore, although Solar Run’s products meet the highest quality standard in the industry, we never forget our main customer group is rural off-grid people who lack affordability, thus Solar Run energy is always thinking about how to make the price more competitive and cost-effective but no compromise on quality, and also Pay-As-You-Go(PAYGo) products take a great place in Solar Run product line. We hope more people could join us and change the world together.

An Overview of Solar Home System

  1. Brief introduction of solar home system

Solar home system: SHS (Solar Home System). Mainly refers to the small photovoltaic power generation system installed in office buildings and residential buildings to supply power to the residents themselves. During the day, the power generation system charges the battery; in the evening, the power generation system discharges the electric energy stored in the battery to realize power supply to household loads.

Its composition is as follows:

 

  • PV modules

Solar panels are the core part of the solar power generation system and the most valuable part of the solar power generation system. Its role is to convert solar energy into electric energy or sent it to the storage battery or drive the load. The quality and cost of solar panels will directly determine the quality and cost of the entire system.

The raw material of solar panel includes cells, glass, EVA, TPT, and aluminum alloy frame.

  • Controller

The solar controller is composed of a dedicated processor CPU, electronic components, displays, and switching power tubes.

  • Battery

Generally, lead-acid batteries, generally 12V and 24V two kinds, in small and microsystems, Lithium Iron Phosphate batteries, nickel-cadmium batteries, or lithium batteries can also be used. Its function is to store the electrical energy generated by the solar panel when there is light, and then release it when needed.

  • Inverter

In many cases, AC power is required.

There are two kinds of electricity, DC and AC. Homes that are connected to utility power use AC electricity. Flashlights, small radios, and automobiles use DC electricity. The direct output of the solar generation system is generally direct current, which needs to convert the DC (direct current) generated by the solar power system into AC (alternating current), so an inverter is required. An inverter is a device that converts direct current (DC) into alternating current (AC).

 

  1. Classification of Solar Home System

Household solar power generation is divided into off-grid power generation system and grid-connected power generation system:

  • Off-grid solar home systems.

It is mainly composed of solar cell components, controllers, and storage batteries. To supply power to AC loads, an AC inverter is also required.

 

( YelloBox—4 rooms lighting and 2 ports for phone charging )

( Mbox — Power home lighting, phone charging, fan, TV, radio, solar torch )

 

  • Grid-connected solar home system.

It means that the direct current generated by solar modules is converted into alternating current that meets the requirements of the commercial power grid by a grid-connected inverter and then directly connected to the public grid.

Grid-connected power generation systems include centralized large-scale grid-connected power stations, which are generally national-level power stations. The main feature is that the generated energy is directly transmitted to the grid, and the grid is uniformly deployed to supply power to users. However, this kind of power station has a large investment, a long construction period, and a large area, and its development is relatively difficult. The distributed small-scale grid-connected power generation system, especially the photovoltaic building integrated power generation system, is the mainstream of grid-connected power generation due to the advantages of small investment, fast construction, small footprint, and large policy support.

 

  1. Advantages of solar home system
  • Solar energy is inexhaustible.

The solar radiation energy received on the earth’s surface can meet 10,000 times the global energy demand. As long as solar PV systems are installed on 4% of the world’s deserts, the electricity generated can meet global needs. Solar power generation is safe and reliable, and will not suffer the impact of the energy crisis or unstable fuel market.

 

(2) Solar energy can be everywhere, and power can be supplied nearby without long-distance transmission, which avoids the loss of long-distance power transmission lines;

 

(3) Solar energy does not use fuel, and the operating cost is very low;

 

(4) Solar home system has no moving parts, is not easy to damage, and is simple to maintain. It is especially suitable for unattended use;

 

(5) Solar home system does not produce any waste, has no pollution, noise, and other public hazards, and has no adverse effects on the environment. It is ideal clean energy;

 

(6) The solar home system has a short construction period, is convenient and flexible, and can add or reduce the amount of solar power capacity according to the demand of the household to avoid waste.

 

  1. Application fields
  • Small power supplies ranging from 10 to 100W are used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc., such as lighting, TV, radio, etc.;

 

( Apollo—Room lighting, radio, phone charging, fan, TV)

 

  • 3-5KW home roof grid-connected Solar Power Generation System;
  • Solar water pump: to solve the drinking and irrigation of deepwater wells in areas without electricity;

(4) Solar water purifier: to solve the problem of drinking water and purified water quality in areas without electricity.

Sometimes we were asked by customers why their solar home system works shorter than it should be when it is fully charged? How to make my solar products working longer?
To answer these questions, we should know about the common features of solar home systems. Usually, it is made of solar panel, controller with battery, home appliances like LED bulbs, TV, fan, etc. The features of solar panel and appliances are relatively stable, and the lifespan is longer than the battery. The solar panel has at least 10 years lifespan, LED bulbs with 50000 hrs (about 11.5 years if use 12hrs/day) lifespan. But for the battery, the service life is influenced more by external factors like temperature and humidity user habits.

The features of the battery:
In Solar Run’s products, we use Lithium Iron Phosphate (LiFePO4) battery. It has the advantages of high safety performance, long lifespan, high-temperature performance, no memory effect, environmentally friendly. But it also has the inevitable defects of ordinary batteries.

  1. Worn out after the lifespan
    Under standard conditions, the LiFePO4 battery has 2000times deep charging cycles, more than 5 years lifespan. After 2000times cycles, the battery will be worn out, and remains only 80% capacity or even less. That’s why we charge the battery fully but the working time is shorter than it should be.
  2. Ionic activity
    When the product is put aside and does not use for a long time. The movement speed of the ions will slow down or crystal. So we should keep the ionic active by using it frequently. In addition, if often over-discharged, the battery lifespan will also be shortened.
  3. Static power consumption
    Sometimes even we do not use the product, we will see the battery level decline. Why? Because the electronic component in the controller consumes power. We call it static power. If the battery level becomes less to a certain degree because of the static power consumption, but still not charged, the battery will be damaged. The battery capacity will decrease or even no use anymore.

Sometimes even we do not use the product, we will see the battery level decline. Why? Because the electronic component in the controller consumes power. We call it static power. If the battery level becomes less to a certain degree because of the static power consumption, but still not charged, the battery will be damaged. The battery capacity will decrease or even no use anymore.

Based on the features of the battery, here are some tips to take care of your solar products:

  1. Do not use the battery frequently. Even if there is over-discharge protection, it’s better to charge the battery before the battery runs out of power.
  2. If do not use the system, turn it off. This is to decrease Static power consumption.
  3. Clean the solar panel regularly. In some places, it is very dusty, it is highly suggested to clean the solar panel at least once a week. If the solar panel is covered by dust, the charging speed will be slow.
  4. If do not use the system for a long time, keep the product in a cool and dry place. And charge the system at least every 6 months. It’s is for keeping the battery ionic active and avoiding battery depletion. This tip is more for distributors, who have products in stock.

What is An Inverter?

1. Introduction

There are two kinds of electricity, DC and AC. Homes that are connected to utility power use AC electricity. Flashlights, small radios and automobiles use DC electricity. In order for you can use solar to operate the appliances, an inverter will convert PV power from DC to AC.

Inverters can be further classified as units that use batteries (UPS) and those that use the utility grid as power storage (Grid-tied). Inverters are now required to possess meters that will indicate their performance and some manufacturers supply remote display units that can be mounted inside the home. It is important to check on your inverter regularly to become acquainted with its operation and performance.

Virtually, today all household appliances and other major electrical fixtures and equipment can be run by an inverter. In the event of a power shutdown, an inverter is extremely useful as an emergency backup power unit, and if optimally charged, you will still be able to use your computer, TV, lights, power tools, kitchen appliances and other electrical conveniences. Of course, this will also depend on the type of inverter used, specifically, the one designed or recommended for powering a combination of high energy-consuming appliances, fixtures and equipment.

The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries which are charged separately. The other configuration is when it is a part of a bigger circuit such as a power supply unit, or a UPS. In this case, the inverter input DC is from the rectified mains AC in the PSU, while from either the rectified AC in the UPS when there is power, and from the batteries whenever there is a power failure.

 2. Applications

Inverters are used for a variety of applications that range from small car adapters to household or office applications, and large grid systems.

  • Uninterruptible power supplies
  • As standalone inverters
  • In solar power systems
  • As a building block of a switched-mode power supply

3. How does the AC inverter work with the Solar Run product?

After the discussion with lots of customers and marketing surveys, we found that many clients, no matter in urban or rural areas, have the demand for both AC and DC electricity due to their need to charge laptops and use their existing AC powered appliances like TV and fan. Meanwhile, they also want to use a DC solar home system for lighting to save more living expenses.

Based on this reason, Solar Run Energy has designed the Mbox solar home system with an external AC inverter optional as the solution. Through this way, diesel generators could be absolutely replaced by clean energy and people no longer need to bear the high cost, noisy and polluted machine. Also, the big capacity Mbox could power the appliances for more than one day, therefore, people could still enjoy their family time even when the rainy day comes.

Solar Cold Chain Provides Fresh Cold Storage Solution for Sub-Saharan Region

cold chain is a temperature-controlled supply chain. An unbroken cold chain is an uninterrupted series of refrigerated production, storage and distribution activities, along with associated equipment and logistics, which maintain quality via a desired low-temperature range. It is used to preserve and to extend and ensure the shelf life of products, such as fresh agricultural produce, seafood, frozen food, photographic film, chemicals, and pharmaceutical products. Such products, during transport and when in transient storage, are sometimes called cool cargo. Unlike other goods or merchandise, cold chain goods are perishable and always en route towards end-user or destination, even when held temporarily in cold stores and hence commonly referred to as “cargo” during its entire logistics cycle.

Modern cold chains manage the temperature of perishable goods from farm to table, maintaining quality and safety in the supply chain, reducing food loss and increasing food supplies. However, the technology is often out of reach in off-grid areas in developing markets due to its cost, a lack of access to reliable electricity, and the wide variety of uncoordinated stakeholders in the broader cold chain.

Solar Run has developed one whole series of solar solutions to keep fresh food and try to help local farmers/ small shop holders to increase income. These solutions will benefit dozens, thousands and even tens of thousands of rural farmers, for those in a world where an estimated 1.1 billion people live without reliable electricity and basic cooling services. Scarcely 4 percent of India’s food moves through cold chains. Roughly half of Nigeria’s 186 million people have little or no access to refrigeration. We estimate that with the cold chain solution, smallholder farmers will be able to increase their annual income by 25% and create more job opportunities for women.

 

Solution 1: solar fridge:

 It comes with a solar controller built-into a 615Wh LiFePO4 battery, which can support 24 hours continuous power for a 100L fridge. It can keep the daily food, including meat, seafood, frozen food at the fresh status and enjoy with the highest nutritional value.

 

Solution 2:  100L / 175L Solar freezer
