FREQUENTLY ASKED QUESTIONS
What kind of location do I need for a solar panels installation?
Solar panels must have unobstructed southern exposure. They must be clear of shading from trees, buildings, and other potential hindrances.
How much space required for solar panel installation?
Each 1 kilowatt of solar panels needs 60-100 square feet of space pending upon PV module category either it is polycrystalline, monocrystalline or thin film/
Where do the panels need to be installed?
In routine practice, solar panels are mounted on the rooftop. But in case if rooftop is already engaged or not sufficient for larger amount of panels other location could be prepare with secure surrounded and dust free area.
What permits are needed for a solar system installation in Pakistan?
There is no need of any permits for solar system installation in Pakistan or energy production unit less than or up to 5 Megawatt.
What kind of maintenance is required for installed solar system unit?
The only maintenance required is time to time Solar panel cleaning upon requirement.
What happens on cloudy days?
During sunny days solar system gives peak output if it is not to warm outside, but can also produce energy from cloud-filtered sunlight. A battery bank can provide a set amount of stored power for a specified period of time.
How much saving using solar/grid hybrid system?
A solar system can help saving in electricity bills up to 80% depending on connect load.
What’s the difference between solar photovoltaic and solar hot water systems? Both types of solar systems capture energy from the sun, solar photovoltaic systems use photovoltaic panels to produce electricity. Solar hot water, or thermal, systems capture sunlight to heat water for domestic use, to heat a swimming pool, or for a radiant heating system.
How long does the solar energy system last?
Solar PV panels are manufacturer-warranted at 80% of power production for 25 years. Other components, such as inverters, Charge Controllers and other electronics, may vary in warranty terms. During the life of the system, there most likely will need to be an inverter replacement at least once, and if batteries are used, if you are using good quality AGM batteries, replacement need every 5 to 8 years.
Can we use solar energy as totally independent source of electricity?
In remote areas where grid connected power is not available, electricity can be stored in batteries and use that power but this will raise investment cost.
