In bright sunlight, a square foot of conventional photovoltaic panels yields around 10 watts of power. However, when shading, spacing and walkway arrangements are factored in, PV systems yield around 5 watts per square foot. That is a handy rule of thumb for roughly estimating area you might need. For example, a 1000 watt system may need 100 – 200 square feet of area. Required area varies according to the type of PV module used.
What is Solar Energy?
Solar Energy is the energy stored in sunlight. Traditionally, Solar Energy refers to the usable form of energy obtained by using rays of sunlight to generate heat or electricity. It is an infinitely renewable resource and unique for its ability to generate energy in the quietest, cleanest, and consistent manner. Nothing can beat the sun for being so cool!
How much space do I need for a solar photovoltaic system?
How many solar panels do I need for an electric solar power system?
Solar system size requirement depends upon your home’s energy needs, available space and overall cost for components and installation. To get an estimate of the size of system for your needs, checkout our standard packages or call us at 042 111 112 886 to schedule a visit of our representative.
How do I know if solar panels will work on my home?
Solar PV energy, unlike other renewable sources, is available in most places. Because, every part of the Earth receives some amount of sunlight. However, certain other factors may effect performance of solar panels. To analyse if solar will yield good results, take a look at the position of your home, particularly your roof. Ask the following questions:
Is there good southern exposure?
Solar panels facing to the south are most effective in energy collection. So, check if the shape or construction of roof allows mounting of south facing panels.
Is the exposure free of shadows of trees or buildings?
Shading on photovoltaic panels dramatically reduces their effectiveness. So, check if taller buildings or trees will directly shade panels or drop debris/leaves on them.
What is the pitch of your roof?
Most roofs, from flat to 60-degrees can accommodate photovoltaic panels. However, it might be difficult to mount them if for some reasons the pitch of the roof is steeper than 60-degrees.
Can I eliminate load shedding with solar?
Yes, you can eliminate load shedding with a hybrid solar PV system.
Our standard systems are designed to eliminate load shedding. The advantages of our solar PV system over other alternative fixes of load shedding include uninterrupted power, negligible operating cost, cleaner source, reliable power, no noise and pure sine-wave regulated output to keep your appliances safe.
Can I replace my generator with Solar PV system?
Yes you can.
You can replace your diesel generator with a solar PV system if enough space is available for mounting of adequate amount of Solar Panels. For most homes, this requirement holds true. And even if it does not you can limit your generator usage to rare occasions such as parties, functions or get togethers (that too only in summers).
What if I buy the components and install it myself?
If you are planning to power up a few lights or a couple of fans then you should be fine. However, with bigger systems comes bigger risks and shock/fire hazards. As solar PV system involves high voltage DC power and very powerful batteries, certain standards need to be followed in its installation.
What if I ask my electrician to install it for me?
Never do it.
Installing solar is very different from installing UPS or appliances. A substandard installation may appear to save you some money upfront. But the risk and danger it carries may result in a bigger loss. And probability of that happening is very high. Look around and you will find lots of failed examples of people trusting electricians and suffering big time.
For a proper solar installation you should only trust professionals. Never trust a freelance electrician or a novice installer with such a big investment. As they may turn it into a huge loss.
Unfortunately, very few companies in Pakistan follow international standards for solar installations. Therefore, at Pantera Energy, our focus has always been to provide high quality services to our clients. Because economy should not mean a drop in quality.
There are so many options available in market. Shouldn't I just go ahead and buy the cheapest one?
Look for economical products not for cheap ones
Going for a 50% drop in price for a 90% drop in performance is a very bad investment. Look for products that provide best value for money. Never trust second hand or sub standard products. It is a long term investment and should be done with care. A penny saved today can result in costing two (or three or four actually) in the future. So always go for warranty backed, traceable, high quality and reliable products by reputed manufacturers.
