Solar FAQs: installation and roof

Questions

• How long does installation take?

  A small project usually takes about a week, depending on payment, equipment stock and site conditions.

• How much roof space do I need?

  A modern panel covers about 2.

• What are L2, L3 and elevated structures?

  L2 and L3 are standard rooftop frames that hold two or three panels per structure.

• Will installation damage my roof or cause leaks?

  Not when it is done properly.

• Which direction and angle should panels face?

  In Punjab, panels should face south, tilted at about 20–30°.

• Can I add more panels later?

  Usually yes, if the inverter has spare capacity and inputs, and your sanctioned load allows it.

• Can I use my existing UPS and batteries?

  Sometimes, but often it isn't worth it.

• Can I get solar in a rented house or a flat?

  Often yes, with permission.

• What does a solar site survey include?

  At the survey we measure the roof, check shading through the year, look at the roof’s condition and access, and note your electrical board, earthing, meter and connection type.
