The position of the solar panels is the most important thing. They can't be blocked from receiving the sunlight. Every shadow will decrease their performance

They have to be placed in the position where the sun shines the most. And it is important to consider the adequate position for the whole year.

Place the posts first and attach metal rails to the posts on your roof. Attach solar panel mounts to the solar panels; the roof-ground mounts will suffice. This step is a little tricky: you have to assure that there is no space between the panels; if there is some, the transmission of energy between the cellars will be lowered.

It is also very important to avoid touching the panels with your feet. You have to use only your hands and carefully.

The next step is to connect them to the inverter. When it comes to inverters, the synchronous solar panel inverter is the best affordable choice.

A battery stores the solar energy and the excess can be sold back to the utility company. In any situation where you do not have enough energy for your house, the utility company will supply the necessary energy through the converter.

I am sure you have understood that you cannot lose in this situation. If you have too much energy, you can sell it; and if it's the contrary, the utility company will supply your needs. And in case anything happens to the grid of the utility company, you will the only one who will be able to use some energy in your city because the battery will still provide you with the sufficient amount of stored energy that you need.

Now that the installation is done, I hope it was not too difficult. The thing is to pay attention to every details to avoid some loss of energy or to have a faster deterioration of the panels than what would be normally expected.
