Benefits
Energy is free of cost Does not cause pollution Can be used in remote areas Many everyday items can be powered by solar Renewable source Less Maintenance Easy to install Technology is improving consistently Visually appealing
05/01/2023
Drawbacks Can be harnessed only during daytime
Solar panels, cells collectors expensive, though rates are falling.
Don’t match power requirements of similar sized conventional power stations
Large areas required , unreliable climate problematic
Large batteries required (For Off Grid systems)

Energy savings
05/01/2023
Factors affecting the cost of solar installations Solar rebates Type of roof Age of roof Labour and prevailing
wage Type of solar panels Added local costs Extras
05/01/2023
Why choose solar? Possible to take advantage of
government rebates Increase property value Protect yourself from increasing
electricity costs Reduce carbon footprint and go green Supply back to the grid/ Rent solar
panels and earn money
