Successful Project


Mr. Potts is a BUILDING OWNER in the UK and wanted a 20k-watt solar power system. 

Mr. Potts called us last week. And he told us about the offset solar system he wanted. He mentioned that the price should be LOW or affordable. 

We went through the MARKET. Got him quality solar panels with impressive warranties. PLUS, we RECOMMENDED a battery, inverter, and charge controller for storing energy. 

Overall, this deal has been VERY SUCCESSFUL. 

Mr. Rehan lives in Egypt and called us for a foldable solar panel with ALUMINUM FRAME and quality solar cells. 

Mr. Rehan CONTACTED our sourcing team for recommendations on solar panels. We asked him to BUY the 300w SOLAR PANEL with an inverter system to RUN home appliances. 

We helped install it on the ROOF to capture the high intensity of SUN energy. And avoid factors affecting the EFFICIENCY. It has been great working with Mr. Rehan!

    People Also Ask About 300w Solar Panels

    1. How much equipment can be run by a 300W solar panel?

    It depends mainly on the TYPE of equipment you want to run. In residential areas, it can empower the lightning system and low-power devices. You must have batteries and a solar CHARGE CONTROLLER with high-efficiency panels to store electricity. 

    2. How much power can a 300W solar panel produce?

    A single 300-watt solar panel can generate 2.5-kilowatt hours per day. That becomes 900 kilowatt hours per year. It is ENOUGH energy to store if you have a battery and a solar charge controller. 

    3. Is it okay to connect six pieces of a 24V 300W solar panel in parallel?

    Yes. It is not a BIG DEAL if you connect. However, you might need a HIGHER operating voltage. It is because such a HIGH power is designed to work at a HIGH voltage of 30 or 32 volts. 

    4. What’s the wattage generated from 4 pieces of 300w solar panels?

    Theoretically, four parallel connected solar panels can produce 1200-watt electricity. But there is one PROBLEM. It is the sunlight that affects it. So, power generation will be less than 1200 watts, as featured. 

    5. What percentage of homes in the United States use solar power?

    According to some, 2.2% of the US homes use solar panel technology to produce renewable energy. It can increase over the YEARS based on the increased POPULARITY of solar cells.
