Eid Mubarak from our family of companies to yours

Rain is actually a blessing in disguise for the solar panel installations. It helps clean the neglected panel surface from days of soil and dirt deposition.

A very pleasant cloudy morning with scanty rainfall in Karachi today. However, it is not a good day for good solar production because of low sunlight.

Overcast weather conditions limit solar output production to up to 20 percent of the rated power capacity, depending on the extent of cloudy morning.

Reach out to us to clarify your questions related to solar energy systems.

Planning your PV System, you should ideally size the PV Array about 20% times the rated power of the Inverter. e.g. 12kW PV system for 10kW inverter.

Solar Panel output is greatly reduced by soiling i.e. panels getting dirty with sand and dust. In Pakistan, Soiling losses contribute to up to 44% of the total efficiency losses of solar power systems.

Researchers at LUMS have observed soiling rates at 0.02 mg/cm2 on solar panels installed at a tilt angle of 30 degrees in the city of Lahore.

Soiling losses are dependant on the tilt angle of the installation and the local geography and weather conditions.

But there is a very simple remedy! Just clean your panels on a weekly basis and ensure that your solar panels are effectively converting the Sun's radiation into electricity.

Raj Enterprises offers very cheap maintenance service plans to keep your investment performing at its peak.

Are you confused about what are Mono and Poly Crystalline Solar Panels and what should you select??

Mono Solar Panels are made of single-crystal silicon ingot, by a delicate process, thus are more efficient but of course more costly.

Poly Solar panels have multiple crystalline silicon ingot which is cheap to produce but have little less efficiency.

Easy to distinguish, Poly Crystalline solar panels are Blue in colour while Mono Crystalline Solar Panels are generally Black.

Poly Crystalline panels are ideal for residential installation.

Not sure at what tilt angle should you have your solar collectors installed?

Researchers at the University of Karachi's Physics department have concluded that the optimal insolation of solar radiation during winters is obtained at Φ + 20° (steep) and during summers is obtained at Φ - 20° (flat)

For fixed installation, the rule of thumb should be to install the solar collectors at the same angle as is the latitude Φ
