V panels should ideally be in full sun from at least 7 am to 4pm They should not be placed in shaded areas and should be kept free from dust and dirt Shading from objects such as trees roof ventilators or antennas will have a large impact on the output of a panel as it changes the flow of electricity through the panel 6 4 Mounting The mounting system should be engineer certified for the area you are in Choosing of right solar mounting system for your project will depend on a few factors Cost availability wind snow load and seismic activity factors for your area are all considerations There are two types of mounting system one is Roof mounting and another one ground mounting 12 Fig 6 4 Solar Power Consumer Guide Version 1 0 AWN Adithyamitra Lights amp Solar Solutions 7 SOLAR POWER SYSTEM LIFESPAN Solar modules have been tested in the field showing small reductions in power output after few years mostly because the glass surface becomes a bit dull and does not absorb as much light Good solar panels usually carry an output warranty of 25 years The electronic components such as inverters being the next most sensitive after panel should last at least 2 to 5 years before requiring refurbishing or replacement Solar Panels Product Warranty 10 Years Power Warranty 25 Years 2 Years Off Grid 5 years On Grid Batteries 3 5 Years Warranty at customers DOD and loading of batteries DOD D
