As the global demand of electricity is increasing day by day, the necessity of establishing power plants is also increasing. Besides establishing conventional energy sources like oil, gas and coal based power plants, non-conventional energy sources like solar based power plants are also establishing gradually. Ground mounted solar power plants require feasibility, environmental assessment, grid connection, siting etc. which is typical for a large industrial project. Implementing a solar power plant project requires comparatively more time than a rooftop residential solar installation. 

Countries having subsidy program like tax rebates, feed in tariffs etc. implement solar farms. Due to availability of solar panel, solar inverters and installation expertise, building a solar power plant is quite convenient at present. On the other hand, the permits and regulations for building a solar power plant or a solar farm vary from country to country and region to region based on federal and stat…

In the process of selection, design and installation of an appropriate solar PV system for your home or business, a professional site assessment is a crucial part. Cost and power output of your potential PV System significantly depend on it. The output of a PV module is directly proportional to the amount of sunlight strikes on it. 
A proper site assessment significantly contributes to determine and identify a number of factors: the site capacity of generating energy, shading issues, how much revenue will be generated from the power plant, return on investment (ROI), rebates and incentives, structural and electrical concerns. The site assessment also significantly contributes to save money in basic energy efficiency improvements and more lucrative methods to organize a solar project on-site. After reviewing the report, you will be able to make well-versed decisions about your project. The site assessment report will help you to bring your goals, budget and energy needs together with th…

In order to design a solar pv system, you need to follow following steps:

1. Determine the amount of electricity (kWh) consumption and the electricity rate
It is important to determine the amount of electricity consumption per year for better understanding the economics of installing a solar system. On your utility bill, your electricity usage is summarized wherein natural gas usage should be excluded. As the path of the sun varies with the seasons, a solar PV system would offset your electricity demands mostly in the summer months. It should be also considered that most utility companies have a tier rate structure based on consumption patterns and state mandates. A small PV system significantly helps to reduce your electricity demands for moving you to a different tier, minimize your rates and saves your money.

2. Determine your available roof space (sq-ft)
Knowing your available roof space is crucialfor determining the quantity ofsolar panels you can actually use. Based on the size of y…

We expect smooth power generation from a solar photovoltaic (PV) system while sun shining. When the sun is out but the system doesn't generate electricity as per required capacity, then we consider the system as problematic. Solar photovoltaic (PV) system occasionally requires troubleshooting as like as other energy systems. The key to your success depends on the strategy you choose for identifying the trouble source. Typically, three problems occur in solar photovoltaic (PV) system. They are-an array problem, inverter problem, or load problem. Concentrating on common troubleshooting problems and solutions can ensure that your system is taking the advantage of summer's sunny days.

Components of a solar photovoltaic (PV) system

Cell, module and array: A typical photovoltaic (PV) cell produces a small electrical output ranges from 0.5W to 2W approximately. As these devices are electrical, we can boost overall output level by wiring them in series and parallel strings. Wiring PV ce…

Solar panels play a significant role for generating electricity. Solar panels generate electricity when exposed to the sunlight. The efficiency of solar panels and generating electricity is strongly influenced when sun exposure to the solar cellis reduced. Dust, dry areas and building up other particles like droppings of birds have significant impact on the amount of generating electricity by solar panels. Cleaning solar panels regularly can significantly increase the overall efficiency of solar panels. Typically, solar panels are self-cleaning. Insufficient care for solar panels can decrease the efficiency of solar panels. Therefore, it is very important to maintain solar panels very carefully.


How to clean solar panel glass Before starting cleaning, you have to shut down your entire system as per instructions or guidelines of your manual provided by your solar panels manufacturer.Cleaning solar panels from the ground is safe. In order to stay on the ground saf…

Inverter is a power converter which converts Direct Current (DC) into Alternating Current (AC). As most of modern appliances operate on 120 volts AC, an inverter plays a key role for your solar power system. It can convert the low voltage DC to the 120 volts AC and also can charge the batteries if connected to the utility grid.

Basically, an inverter can supply three types of power. They are as follows:

Usual or typical power: An inverter has to supply usual or typical power on a steady basis which is continuous rating. It is comparatively lower than the surge power. For example, after the first few seconds, a refrigerator pulls this power to start up the motor.

Surge or peak power: Supplying maximum power by an inverter for short time period is called surge or peak power. Typically, it ranges from few seconds up to 15 minutes or so. For example, we can say about electric motors like pumps which require higher startup surge while running.

Average power: This power is comparatively lower…
