Solar panels are also known as photo-voltaic (PV) modules consist of a number of photo-voltaic cells mounted together in a frame. They convert sunlight to direct current or electricity through the photovoltaic effect. Faint horizontal lines called metal ‘fingers’ collect moving electrons which are then delivered to thicker, vertical metal lines called ‘busbars’. These busbars collect all the electrons and are connected to the next solar cell.

  • Roof Space
  • Budget
  • Future Energy plans

For a residential customer, a net-metered Solar PV system of 5 KW inverter matched to a 6.6 KWp of modules (i.e. 20 panels of 330 Wp) is the ideal size for any typical household. Always consider a bigger size owing to the advantages in system cost and better savings that are invariably associated with a big system.

Yes! Solar power panels will work when it rains, or it has a shade.

Although production is affected during rain, the panels will still produce power and this, in turn, will help you save money even if it is raining.

  • The maintenance for a PV system is typically quite low as it involves mostly cleaning of the panels.
  • We also recommend an annual general check-up to be performed by a local installer to identify any risks in electrical wiring.
  • If you are losing efficiency and still under a performance/power output warranty, then can call your solar installer. They will send someone to assess the situation and fix or replace the panels.
  • If your panels have sustained physical damage, that's often covered under a separate equipment warranty, or under your homeowners' insurance.

No Installation of Solar Panels can be done minimally and will not damage your roof.

A residential system of 5-10 KW will take less than a week to complete the installation.


For commercial PV system, a typical 100 KW rooftop system will take about 1 month and for large MW size ground-mounted projects will go up to 4-6 months depending on the site conditions etc.

Yes you can. There are many schemes ongoing in several states with subsidy for residential PV systems. One needs to talk to a local installer or log into your local utility company website for solar rooftop to be fully aware of the subsidy and special schemes working.
