Successful Project


Mr. Potts runs a hotel in the UK. And he wanted to tackle power outages. 

Mr. Potts was distraught due to high energy requirements. So we recommend a grid-tied system with a battery and string inverter. 

After installation, he was super happy with our solar system installation. He promised to use our services again. 

Mr. Vladimir Belongs to Russia. He wanted a complete off-grid solar power system. 

Mr. Vladimir has to run the household appliances. Therefore, he needed an off-grid system to produce enough electricity. 

We have the best quality off-grid system. And we installed it. Now, he is producing excess energy. And can cut energy costs.

    People Also Ask About On-grid Solar Panels

    1. Is a grid-tied solar system worth it?

    Yes. The grid-tied solar system is worth your MONEY. You produce excess ENERGY. Have a backup battery storage system. And use it when the sun is not around the SOLAR ARRAY.

    2. Can you have batteries for the grid-tied solar systems?

    Yes. Usually, Grid-tied solar systems have battery backup. It is a WONDERFUL idea to add a BATTERY STORAGE. Because if your electric GRID does not work, you will still have enough power in the BATTERY BACKUP. 

    3. Does On-Grid solar panel installation ensure uninterrupted power?

    In an On-Grid solar system, you need a BATTERY system for RENEWABLE energy storage. The small inverter will decrease as the ON-GRID solar power system goes down. The battery bank would be there to save EXCESS power. And use it.

    4. Can you install a grid-tied solar panel system with batteries that remain on when the grid goes down?

    Yes. That works perfectly. You need to measure the POWER DEMANDS for the solar panel systems. And then proceed to meet your POWER DEMANDS.

    5. How much electricity will an average household save over time by switching to grid-tied solar panels during peak usage hours?

    It depends on your ELECTRICITY usage. If you use more, the power consumption will be more. And energy savings would be less. That is the SIMPLE FORMULA for grid-tied solar systems.

    Focus on your business & let our team of experts handle the rest.
