Successful Project

Mr. Dimitri is a store owner and wanted 4 100w polycrystalline solar panels. 

Mr. Dimitri is from Italy. And called our team for 4 100w polycrystalline solar panels. We researched the best poly panels. And we got him the exact poly panels he needed. 

After installation, he was super happy. Now he stores more electricity. And fulfills his demands by cutting expensive bills. 

Mr. Philips is from the UK and contacted our team for a 20K watt higher efficiency solar setup. 

Mr. Philips runs a superstore with high demands for more energy production in less space. Our experts got the idea of monocrystalline solar panels. 

We installed it at his location. And we helped him produce extra energy. He made it possible with thin film solar cells. Last week, he made a new order for polycrystalline modules.

    A typical monocrystalline solar panel has a LIFESPAN of 20 to 25 years. Multiple factors might affect it. For example, the operating conditions and the maintenance.

    2. Are monocrystalline solar panels more efficient in warm weather?

    In warm weather, solar panels might lose some power output. They MAY not generate the HIGH power as well. Therefore, you should know before installing the solar panels.

    3. Do monocrystalline solar panels work in the shade?

    Yes. They work in the shade. It is because of LOW-LIGHT performance. You get better energy production. And higher performance even in the SHADES.

    4. What is the difference between polycrystalline and monocrystalline?

    Polycrystalline solar cells are often blue in color. There are multiple silicon crystals in polycrystalline solar cells. They have less efficiency. 

    On the other hand, monocrystalline has black cells. And a single crystal silicon structure. They have a HIGHER efficiency.

    5. Is it better to connect solar panels in series or parallel?

    Parallel solar panels have BETTER energy production. So, it is better to connect the positive and negative ENDS in parallel design. And produce high energy.
