How to be sure your home supports installing solar panels


Solar power generation has a lot of scope in India. The geographical location of the country is a huge advantage. You can save on your monthly electricity bills by almost 70% in an economical solar panel frame and a solar panel will last around 25 years. Thus, rooftop solar panels are becoming a popular choice for budget and environment conscious customers in India and across the globe.

Check the condition of your roof

Before installing a solar panel on the roof, the roof should be carefully inspected. If the roof is weathered or damaged, the installation of a solar panel is not possible. If your roof needs repair or restoration work soon, it is not advisable to install solar panels as they will need to be taken down for the restoration work. It is advisable to invest in repairs and restoration before opting for a rooftop solar panel installation. Also check if your roof is shade-free and has enough space to accommodate the solar panels. Ideally for installing rooftop solar panels, your roof should receive sunlight throughout the day or most of the day (midday/peak) to achieve maximum efficiency.

Check the slope and direction of the roof

The slope of the roof is a major factor contributing to the efficiency of a solar panel. A slope of 10 to 30 degrees is ideal and allows good drainage of rainwater. A north-facing roof is preferable for rooftop solar panels. Panels installed on north-facing roofs will generate the maximum amount of electricity with high efficiency.

Check the load capacity/weight of the roof

Solar panels increase the load on the roof; therefore, it is important to determine the load capacity of the roof before installing solar panels on the roof to avoid accidents. A professional evaluation is recommended. A professional expert can inspect the load bearing capacity of the roof and suggest if there is a need for additional support to increase the stability of the roof.

Determine consumption and needs

Different domestic households have different energy needs based on electrical appliances, gadgets, machinery, and lighting. Before installing a solar panel on the roof, it is advisable to calculate the energy needs of your building to select the right number of solar panels to install. A standard solar panel consists of 36 to 72 photovoltaic cells, and each cell provides about 0.5 V of power. This can be used to calculate the number of panels needed for a building’s energy needs.
