New rooftop solar installations in India fell to a four year low in the first half of 2020 due to policy changes, financing costs and the impact of covid-19 pandemic slowing India’s transition to a green energy regime. Only 473 MW of new rooftop systems were installed between January and Read more
Tariff: The tariff structure must be clear in Power Purchase agreement. Tariffs can be fixed for the entire term or variable. Power purchase: The off-taker is obliged to buy certain amount of energy every month during the PPA term. Payment: The off-taker must pay a pre-determined tariff rate multiplied by Read more
PPA default occurs when there is a breach of contract between developer and off-taker. The off-taker may default due to a failure to make agreed payments, failure to perform the contracted obligations, provision of incorrect information in the initial PPA agreement, and shutdown of the off-taker’s business. The developer will 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
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
PV module: Turns light into electricity. A group of solar cells in a sealed unit. Grid-tied inverter: An inverter that reads the voltage of the grid and produces as much power and current as it can, regardless of loads. For example, a 5kW inverter can only put out 5kW. Grid-tied Read more
The off-Grid system relies heavily on better-abled storage systems. Battery: Stores energy by chemical reactions. Most stand-alone PV systems use lead-acid batteries. Flooded lead-acid battery: A battery that has a liquid electrolyte (fluid) and uses chemical reactions between lead and acid to store energy. Sealed valve regulated flooded lead-acid battery: Read more
