The top ten uses for solar panels include
heat for your home
power pumps
indoor and out door light battery charging which can be a
beneficial if you have a reserve battery bank that
is charged through the day while sunlight is present and is used
through the nighttime hours. It can also be
used for simple solar panels to collect sunlight and convert it
into electricity.
powering your home, camper, cabin, tool shed, or any other building
for that matter.
when heating swimming pools, a solar hot water heating system
utilizes the solar hot water heating panels,
that can be mounted on your roof to collect the sun’s heat and then
is circulated to the pool.
Solar panels are also being used in space exploration and other
forms of transportation.

Advantages
Solar street lights are independent of the utility grid. Hence, the
operation costs are minimized.
Solar street lights require much less maintenance compared to
conventional street lights.
Since external wires are eliminated, risk of accidents are
minimized.
This is a non polluting source of electricity
Separate parts of solar system can be easily carried to the remote
areas
It allows the saving of energy and also cost.
Disadvantages
Initial investment is higher compared to conventional street
lights.
Risk of theft is higher as equipment costs are comparatively
higher.
Snow or dust, combined with moisture can accumulate on horizontal
PV-panels and reduce or even stop
energy production.
Rechargeable batteries will need to be replaced several times over
the lifetime of the fixtures adding to the
total lifetime cost of the light.
