how much panels do I need?

Every house is different, every family is different. Not only the quantity and profile of energy consumption is different, but also the shape, size and position of the roof of every house. Through experience we know that the majority of errors in the purchase process of solar panels occur in the initial phase when dimensioning the solar installation. For as many solar kits there are available in the market, integrating solar in each house is still a customization issue.

You probably already have seen that revosolar offers many types of solar kits with different connection possibilities (net-balance, assisted-solar, isolated-solar). Now it is time to be precise and calculate exactly how many solar panels you need and how and where they can be mounted on your roof. Taking into account the sun position, eventual shades, type of roofing, profile of electrical consumption and of course your specific wishes and conditions.

To start, observe the table below and look for the annual electricity consumption in kWh from your utility bills. Select the number in the column on the right which aproximates most to your consumption. The table indicates horizontally how many panels you would need, the total surface and the nominal power of your solar installation;
