As our stock is kept at a warehouse and we do not offer a walk in store, we accept EFT payments on invoices. We do allow our customers to browse components at the warehouse before making payments based on prior arrangements with our sales team. The warehouse is only for stock taking and distribution, unfortunately, direct customer card or cash payments are currently unavailable. Full payment should reflect before any component can be dispatched at the warehouse.
We deliver by the means of our own company delivery or with a 3rd party delivery service such as The Courier Guy or Innovative Logistics in Gauteng. For outside of Gauteng, we make use of a 3rd party logistics company to conduct collections and deliveries. We do not recommend solar panels to be in transport and we usually see if we can make solar panels available with suppliers locally in your area if outside of Gauteng. This is due to the risk of breakages on solar panels as well as the higher costs to transport solar panels outside of Gauteng.
All our products are sold without installation services except if it states otherwise on the product. We supply installers and the public with affordable solar components. But, we can assist with installations if required by our recommended solar installer contractors when required.
We can provide you with solar installers in Gauteng and Western Cape. We make use of solar installer contractors who conducts all our residential solar installations for us. We have accredited solar installers in most regions that we can recommend where our own installers are not available.
It depends. If you want to go completely off the grid, you will save 100% on all your electrical expenses and be completely independent from Eskom. If you install a smaller solar panel kit, you can also reduce your electricity bill. It all depends on how many devices will be powered from solar and how many devices will remain on the grid. Either way, you can save up to 50% on average by converting to solar panels or even 100% when you fully go off the grid.
You can save up to 100% with hot water needs in your home by using a solar geyser. Depending on the size and the specific solar geyser and if you’re not going to use an electrical element, you can achieve this very easily. For the average home, you can save 45% on your electricity just by installing a solar geyser.
An electrical geyser can add up to 45% of your home’s overall electrical bill. We offer affordable solar geysers which is a much better option to install than the standard electrical geyser. It is a small investment but in the long run, the solar geyser basically pays for itself while you save money on your electricity bills.
We recommend a good brand battery that offers good after sales service with a 5 to 10 year warranty range. Our recommendation would be to invest in a lithium phosphate battery type that will last for 10-Years or longer. It is a best practice to install a battery that has a battery management system compatible with the inverter that it will be used on. The standard battery we would recommend is a 1C battery (battery can charge and discharge current similar to it’s rated capacity).
Selecting the right solar kit for your specific needs depends on several factors, including your energy consumption, budget, location, and goals. Here are some steps to help you determine which solar kit is right for you:
- Assess Your Energy Needs:
- Calculate your average monthly and yearly electricity consumption. You can find this information on your utility bills.
- Identify your energy goals, such as reducing your electricity bills or becoming completely energy-independent.
- Evaluate Your Location:
- Determine your location’s solar potential by assessing the amount of sunlight it receives. Online solar calculators can help with this.
- Consider local climate conditions, shading from nearby trees or buildings, and the orientation and tilt of your roof.
- Budget Considerations:
- Determine your budget for the solar kit, including installation costs.
- Investigate available financial incentives, such as government rebates, tax credits, or net metering programs, that can help offset the upfront cost.
- Choose the Type of Solar Kit:
- Grid-Tied Solar Kit: If you want to reduce your electricity bills and potentially sell excess power back to the grid, a grid-tied solar kit is a common choice. This kit connects to the utility grid and does not typically include energy storage (batteries).
- Off-Grid Solar Kit: If you are in a remote location without access to the grid or want to be completely self-sufficient, an off-grid solar kit with energy storage (batteries) is suitable. It allows you to store excess energy for use at night or during cloudy days.
- Hybrid Solar Kit: This option combines grid-tied and off-grid capabilities, allowing you to store excess energy while remaining connected to the grid for backup or additional savings.
- System Sizing:
- The size of your solar kit should match your energy needs. Calculate the system size (in kilowatts, kW) based on your electricity consumption and available roof space.
- Consider the efficiency and output of the solar panels included in the kit.
- Quality and Components:
- Investigate the quality of the components included in the kit, such as solar panels, inverters, mounting hardware, and wiring. High-quality components can lead to better long-term performance and durability.
- Warranty and Support:
- Check the warranties provided by the kit manufacturer or supplier for both equipment and installation.
- Ensure you have access to reliable customer support and maintenance services.
- Installation:
- Decide whether you want to install the kit yourself or hire a professional installer. Professional installation ensures proper system setup and compliance with local regulations.
- Permits and Regulations:
- Determine if there are any permits or regulations in your area that may affect your solar installation. Local building codes and utility requirements can vary significantly.
- Compare Multiple Quotes:
- Obtain quotes from multiple solar kit providers and installers to compare prices, equipment, warranties, and services.
- Environmental Impact:
- Consider the environmental benefits of using solar energy, such as reducing carbon emissions and reliance on fossil fuels.
Ultimately, the right solar kit for you will align with your energy needs, location, budget, and goals. Careful planning, research, and possibly consulting with a solar professional can help you make an informed decision and maximize the benefits of solar energy for your specific circumstances.
The total cost of solar panel kits depends on how large the home is, how many people live inside the home and how the people use energy. There is not a one size fits all solar panel system that fits everyone available. Solar Panel kits can start from R20000 up to millions of Rands, depending on how much power you require and how much you’re willing to invest.
The simple answer to this question, 20 years. This is a standard warranty period for the majority of solar panels on the market today. Solar panel warranties cover physical defects in solar panels for about 10 to 25 years. There are also certain warranties that guarantee a specific amount of power output, which is also, generally, for 25 years. Certain solar panel warranties will guarantee that the solar panels will function at a minimum efficiency of 80% or more. This is at the end of the 25 years. Basically, the decrease of solar panel efficiencies is less than 1% each year.
You might have to look into replacing your inverter in about 15 to 25 years. This depend on the type of inverter and if it is a quality inverter or not. Inverter warranties range from 1 to 25 years depending on the manufacturer and how good inverter it is. Basically, you get what you pay for when it comes to inverters. We recommend investing in a good brand inverter with good aftersales support locally to South Africa.
Depending on how you use your batteries and the type of battery, batteries will typically need replacement in 3 to 15 years. Lead-acid batteries can last 1 to 5 years depending on their usage and if they stay in their temperature range and has not been discharged completely for too many cycles. However, lithium-ion batteries can last for an average of up to 15 years and some even longer if maintained properly.
It is basically, using 1000watts of power or electricity in a period of an hour. If you power a 100watt light bulb for one hour, you are basically using 100watt hours. If you power the 100watt light bulb for 10 hours, you’re at a 1000watts per hour or 1 kilowatt per hour. A hairdryer is running at 1000watts, if you power it for one hour, that will consume 1 kilowatt per hour or (kWh). All electrical appliances have different electricity ratings and how many watts they will consume every hour. Wattage multiply the amount of hours will give you the kWh per hour.
A hybrid inverter, also known as a hybrid solar inverter or a multi-mode inverter, is a type of inverter used in solar photovoltaic (PV) systems that combines the functions of a grid-tied inverter and an off-grid inverter, along with additional features to manage energy storage. It is a versatile device designed to work with solar panels, batteries, and the electrical grid.
An off-grid inverter, also known as a standalone inverter or independent inverter, is a critical component in off-grid solar photovoltaic (PV) systems. It serves the purpose of converting direct current (DC) electricity generated by solar panels or other DC sources, such as wind turbines or batteries, into alternating current (AC) electricity for use in homes, cabins, or remote locations that are not connected to the electrical grid. Off-grid inverters are specifically designed to operate independently from the grid and are an essential part of off-grid power systems.
A grid-tie inverter, also known as a grid-connected inverter or grid inverter, is a type of inverter used in solar photovoltaic (PV) systems that are connected to the electrical grid. Its primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be synchronized with the grid’s frequency and voltage. Grid-tie inverters play a crucial role in grid-tied solar systems, which are the most common type of solar installations in urban and suburban areas.
When choosing between monocrystalline and polycrystalline solar panels, it’s important to consider your specific needs, budget, and preferences. Both types of panels have their advantages and disadvantages, and the right choice depends on your individual circumstances. Here’s a comparison to help you make an informed decision:
Monocrystalline Solar Panels:
Efficiency: Monocrystalline panels are known for their high efficiency. They tend to have a higher efficiency rating compared to polycrystalline panels, meaning they can convert a greater percentage of sunlight into electricity. This makes them a good choice if you have limited roof space or want to maximize energy production.
Space Efficiency: Monocrystalline panels are also more space-efficient. They generate more power per square foot, which can be advantageous if you have limited roof space for your solar installation.
Aesthetics: Monocrystalline panels typically have a black or dark appearance, which some homeowners find more visually appealing compared to the blueish tint of polycrystalline panels.
Longevity: Monocrystalline panels often have a longer lifespan than polycrystalline panels and can come with longer warranties.
Higher Cost: Monocrystalline panels are usually more expensive upfront compared to polycrystalline panels, which can make the initial investment higher.
Polycrystalline Solar Panels:
Lower Cost: Polycrystalline panels are generally more affordable than monocrystalline panels, making them a cost-effective choice for those on a tight budget.
Slightly Lower Efficiency: Polycrystalline panels are slightly less efficient than monocrystalline panels, meaning they may occupy more roof space to produce the same amount of electricity.
Adequate Performance: Polycrystalline panels are still highly capable of generating electricity and are suitable for most residential and commercial solar installations.
Blue Appearance: Polycrystalline panels typically have a blueish tint, which some homeowners may not find as visually appealing as the dark appearance of monocrystalline panels.
In summary, if maximizing efficiency and space is a priority, and you have a higher budget, monocrystalline panels may be the better choice. On the other hand, if cost savings are paramount and you have ample roof space, polycrystalline panels can be a practical and cost-effective option. Ultimately, both types of panels can generate clean energy and contribute to reducing your electricity bills and carbon footprint. It’s essential to consult with a solar installer to assess your specific needs and find the best solution for your situation.
