Half cells involve deliberately cutting a fully processed cell into the half with very advanced laser machines. Half cells are being adopted quickly, thanks to the fact that from a manufacturing point of view only minor changes are needed to include laser machines. Half cells improve module performance and durability Read more…
Silicon solar cells are metallised with thin strips printed on the front and rear of a solar cell; these are called busbars and have the purpose of conducting the electric direct current (DC) power generated by the cell. Older solar cells typically had two busbars; however, the industry has moved Read more…
Solar leases and solar PPA are financial setups wherein the homeowner does not own solar energy installation on their roof, it is owned by the lease or PPA company. Let us look at the difference between the two to understand which is the best fit model for your personal needs. Read more…
To get a Solar PV system installed, it is important to understand the various components and factors that are in play.Given the size of the investment, it is absolutely crucial to know everything about the product and its specifics, so better decisions can be made when it comes to making Read more…
In the case of PV On-Grid systems, the system sizing depends on profitability, the energy price or feed-in tariff, available mounting area and approved or connectable PV power. Factors affecting design The most important requirement is the roof orientation Optimal inclination angle between 30 – 45° Transmission possibility of a Read more…
Given the basic requirements, while planning any type of Solar PV System, the off-grid system differs in design in regard to certain additional components.  Dry and ventilated storage place for batteries, if possible protect against low temp (optimal around 20°C) Thermal systems Additional roof statics approx 50kg for 1 installed collector (40kg collector, Read more…
In general deviations in the system inclination between 0-45° are not counted as being problematic and can be compensated by the expansion of installed power by addition on solar panels or solar collectors (this applies particularly to the thermal solar systems). The table below depicts the various different roof inclination Read more…
Accelerated depreciation is a method of depreciation used to depreciate the assets in a manner that greater deductions are allowed in the first few years. Accelerated depreciation can reduce costs during a company’s start up year. By increasing the deductions taken during the first few years of business, you will Read more…
Having a solar PV system requires one to conduct an annual inspection of the system, usually before summer. But in general, there are no costs incurred for wear and tear of materials, except the PV inverter with expected 10-15 years operating time. Damages to the components are generally low. In Read more…
Proper maintenance ensures that solar system life is preserved for as long as possible and the original conditions of the system are sustained while compensating for normal wear and tear. Solar systems require little maintenance as compared to other electric systems such as diesel generators; however, they are not maintenance-free. Read more…
