Home battery
Home battery for both the residential and commercial market.
What maintenance is required for a solar battery?
 
There should be sufficient space and ventilation when the battery is installed. After installation, minimal to no maintenance is needed.
Are there any government incentives for installing a battery storage system?
 
At the current moment, no.
Can a battery power my entire home during a power outage?
 
A high-quality home battery can provide enough power to keep your lights on, refrigerator running, and other appliances operational during an outage.
Is it worth investing in a battery storage system?
 
In our view it is. Once you are able to store energy on a battery storage system, you will find yourself in a situation where load-shedding no longer affects you. The increased efficiency of solar energy is in itself enough reason to consider the solar battery. This is going to make a big difference both financially and in terms of comfort.
How much does a solar battery storage system cost?
 
Battery prices depend upon the storage capacity. You can find out more about prices on our battery page.
Can I add a battery storage system to my existing solar panels?
 
Yes, you can add battery storage and Soly can provide one that is suitable for your power sys.
What is the lifespan of a solar battery?
 
Soly guarantees teminly 6,000 charging cycles while providing a 15-year product warranty. One charge cycle represents the full charging and discharging of the battery.
How long can a battery store solar energy?
 
Once the power is stored in the home battery, it can be used immediately or at a later time. There is no time limit attached to this. If you then still have a surplus of generated energy, while battery storage is maxed out, you can reinject the energy to the energy grid.
What are the advantages of having a battery storage system?
 
Solar panels will make us less dependent on the energy grid. About 30 to 50 per cent of our power consumption, on average, comes directly from your solar system. The home battery offers numerous additional benefits, such as:
  • Higher efficiency of own solar energy
  • Even less dependent on the energy grid
  • Less sensitive to impact of load-shedding
  • Reduces home carbon footprint
  • Reduced electricity bill
How does battery storage work with solar panels?
 
Do you already possess solar panels? Great job! Thanks to solar panels, your dependency on the grid reduces big time. However, once the sun goes down, you'll still be in need of energy from the traditional grid. Thanks to battery storage, your dependency on the grid is limited. You’ll be able to store the surplus of power generated from your solar panels, and use it later on.
Do I need battery storage?
 
You may not need a battery as a solar energy system can work without it. There are advantages to having solar battery backup for specific energy solutions, though not required for everyone. A backup battery is useful for when the grid is unavailable or when you want to minimise your electricity usage. For example, making use of stored solar energy can help decrease your electricity bill and your dependence on the grid itself.

Questions regarding solar panels.
Can I install solar panels myself or should I hire a professional?
 
Although it is practically possible to install the solar panels yourself, we always recommend a professional company to install your solar panels for safety and quality reasons. This way you can be sure that all safety standards have been taken into account. Moreover, all warranties expire if you install the solar panels yourself.
What are the requirements for solar panels?
 
  • Only new and unused solar PV panels qualify, to ensure that the capacity is in addition to what the country already has in place. The panels can be installed as part of a new system, or as an extension of an existing system.
  • Only solar PV panels with a minimum capacity of 275W per panel (design output) qualify for the rebate. Other components of a system – batteries, inverters, fittings or diesel generators – and installation costs do not qualify. Portable panels will also not qualify.
  • Solar PV panels must be installed at a residence that is mainly used by an individual for domestic purposes. The installation will have to be proved with a certificate of compliance in terms of the Electrical Installation Regulations, 2009 to ensure safety of the installation and compliance to electric regulations.
  • The solar PV panels must form part of a system that is connected to the mains distribution of the private residence.
  • The rebate applies to qualifying solar PV panels that are brought into use for the first time in the period from 1 March 2023 to 29 February 2024.
What can be claimed for incentives of solar panels?
 
Individuals will be able to claim a rebate to the value of 25% of the cost of new and unused solar photovoltaic (PV) panels, up to a maximum of R15 000 per individual. For example, a person buys 10 solar PV panels, at a cost of R4000 per panel (so total cost of R40 000). That person would be able to claim 25% of the cost up to R15 000, so R10 000. A different person is able to buy 20 panels at a cost of R4000 per panel (so total cost of R80 000). The calculation of 25% adds up to R20 000, but they can only claim R15 000.
Can I expand my solar panel system in the future?
 
Sure you can. Our solar systems can be expanded to meet higher power demand.
Can solar panels be installed on any type of roof?
 
No, unfortunately not. Your roof needs to be stable and robust. You can check out our online tool to check out if your roof is suitable for solar panels.
What happens to solar panels during extreme weather conditions?
 
If the solar panels are installed correctly, you will not have to worry about the effects of extreme weather conditions. The solar panels are built for these kinds of circumstances.
How long do solar panels last?
 
In general solar panels last at least 20 years. At Soly we provide an extended 25-year product warranty. This way you have a lot of certainty about the quality of your solar system.
What is the efficiency rating of solar panels and does it matter?
 
The efficiency of solar panels indicates the percentage of sunlight that can be converted by the solar panel into solar energy/direct current. This figure is important because a higher return from sunlight ensures that you will have a faster return on your investment. Normally, the efficiency of solar panels is between 15 and 20 percent. With Soly, the module efficiency is higher, at 20.5 percent.
How do I choose the right size and number of solar panels for my home?
 
We have an online tool in which you can simply fill in your current electricity consumption per year. Based on data on your location, we will then give you a no-obligation advice on the number of solar panels, the costs, yields and payback time. This way you are fully informed about all the possibilities of solar energy.
Is it cheaper to lease or buy solar panels?
 
Buying solar panels is a one-time upfront investment, while renting solar panels is a long-term agreement with monthly repayments. The initial investment of buying solar panels is quite considerable all at once, whereas with solar panels for rent, the solar panels are installed on the roof 'for free'. However in both instances after the installation of solar panels is completed you will start saving immediately.

You’ll be able to store the surplus of power generated from your solar panels, and use it later on.
What is the average kWh of a solar panel?
 
Soly mainly makes use of Jinko Solar Panels (visit product page). One panel has the capacity of 350WP (watt-peak). The average kWh (kilowatt per hour) will vary between the seasons of high and low sun peak. However, let’s say on a good day, you average 8 hours of sunlight. Multiply that by 350 watts from a solar panel =  2800 watts or roughly 3 kWh per panel per day.
What happens to solar panels once they reach their lifespan?
 
Solar panels may either be reused or recycled. If reusing is not an option, then making use of the parts is the next step. The materials themselves, such as aluminium, or glass are valuable and will remain recyclable. The goal of renewable energy is to remain as sustainable as possible with little to no waste.
How do solar panels work?
 
Solar panels are solid- state devices which are made from thin layers of semiconducting materials, mostly silicon to form solar cells. When exposed to light the solar cells generate electrical chargers which produce electricity. Several cells are placed together and covered by glass to form a panel, as a single cell alone does not generate a lot of electricity. The solar panels are then placed together on a surface where optimal light from the sun can be absorbed. Solar panels are low maintenance and are reliable pieces of equipment as they have fixed parts which do not require movement. The solar energy system does not produce any gas and there is no noise generated from this process, which makes the solar energy system an environmentally friendly energy production.
What are the environmental benefits of solar?
 
Solar energy provides significant environmental benefits when compared to traditional fossil fueled power stations, such as coal. Coal is detrimental to the environment and releases toxic substances into our air and water, such as nitrogen dioxide, sulphur dioxide and mercury. However, solar energy is produced purely from the sun resulting in no CO2 emissions. It has a domino effect that reduces the reliance on coal, which reduces our carbon footprint and helps mitigate climate change. Solar energy also saves thousands of litres of water as opposed to conventional power stations’ high water usage.

Why do we need location data to make a solar plan?
 
Your specific geographical location contributes considerably towards solar irradiation and is important to know when designing a solar energy system. Solar irradiation is the amount of energy emitted from the sun onto the surface of the earth and it varies across latitudes. South Africa is one of the countries with the highest solar irradiation levels in the world. Optimal solar panel placement increases the efficiency of the solar energy system which allows for more energy to be absorbed and higher energy yield. Have a look at the map to see the irradiation levels of your location. Red means high, green means (relatively) low.
What does a complete solar system consist of?
 
Your own solar energy system consists mainly of three components:
  • Solar Panels mounted onto a roof or structure generates electricity when exposed to sunlight.
  • From the solar panels, electricity flows into the inverter. This component will convert DC (direct current) power to AC (alternating current) power. An inverter ensures the quality and safety of the power coming out of your solar energy system and optimises the different conditions to maximise the amount of energy generated.
  • If your solar panels generate more energy than you are using at that moment, the remaining energy stores in a battery (if desired).
Will I be able to go fully off-grid?
 
Your business will still be connected to the electricity grid, but whenever the sun is shining or you have energy stored, you will only be using your own solar power. During power outages or load shedding, you will be self-sufficient for hours and won’t need to fall-back on a polluting, noisy diesel generator.

Residential
Questions regarding solar solutions for the residential market.
How long does it take to install a residential solar system?
 
Usually we will be able to install a residential solar system within one working day. However, this depends upon the capacity of the solar system and the timing for installation.
How much does a residential solar system cost?
 
The price of a residential solar system depends on the capacity of the system. We have a convenient online tool where you can calculate the solar panel price for your home within a matter of minutes.
How do I know if my roof is suitable for solar panels?
 
All roofs are different in structure, size and orientation. Ideally, the orientation of the solar panels placement in the Southern Hemisphere will need to face a Northerly direction to receive optimal energy, though if the roof structure does not allow for optimal placement of the solar panels then there are other options which are considered for the loss of efficiency, for example adding a roof mount or extra solar panels. Your roof also needs to be free from shade from trees, mountains or other buildings. Most roof structures are stable and reliable for solar installations. A structural engineer will have to look at the roof to ensure it is suitable for installment.

How many solar panels are needed to provide sufficient electricity for my property of business?
 
The number of panels installed is based upon factors such as; the structure and size of the roof or mounting system, the required amount of energy, and the orientation and location of the roof. Each roof is unique regarding these factors mentioned, therefore, the number of panels will vary. Solar panels come in wattages ranging between 150 watts to 370 watts per panel. (See Average kWh solar panels.). The number of solar panels is not an accurate determination of how much energy a roof can obtain, but rather the amount of wattage of each panel and the required energy consumption.
