Within this section you will find • • • • • • • • The cost of a rooftop solar PV system depends on the function it serves (to feed power into the grid, to support the load during a power failure, etc.) and incentives/subsidies available. It should be noted that all solar PV systems function by matching the from some other source.

Therefore the system has to be integrated with the grid, a battery backup, or a diesel generator. Types of rooftop solar PV systems Rooftop solar PV systems are of 3 types: • Grid-tied – These systems are designed to work with the grid alone. Thus, it is a combination of solar PV and grid. As these systems depend on the reference voltage provided by the grid for their operations, grid-tied systems do not work when the grid is down.

• Grid-interactive – This system works in conjunction with either a battery backup or diesel generator to support the load even during a power failure. • Off-grid – Off-grid systems are designed to operate independent of the grid, these systems sync with a diesel generator and/or batteries.

Battery based systems used to be of smaller capacity due to the cost involved, but the rising cost of other power sources, and the lack of power at any cost has seen a steady increase in battery based system sizes The difference between the systems lies in the kind of inverter used, and the inclusion of batteries. As various vendors use different terminology for these systems we urge you to verify the functions of the offered system rather than going by the name alone. Component Cost of Rooftop PV systems At Solar Mango, we are regularly asked the cost break-up and particulare of rooftop solar power plants.

Prospects for Further Cost Reduction One of the questions we are regularly asked is if project cost is likely to reduce significantly in future, as the price of solar PV modules has seen a substantial decrease in recent years. Though PV modules have decreased in price they form only half the cost of the total project; further decrease, if any, will only affect that portion and therefore impact on total project cost will be limited. The prices of the other components have not decreased the way the price of PV modules has decreased. Therefore we do not expect to see much reduction in project cost in the near future.

Variations in Pricing Prices of solar PV systems offered by various vendors can differ significantly. There can be several reasons for the variations in price, such as • Overstatement of capacity – Some vendors advertise a rooftop system with 1 KW modules (solar panels) and a 5 kW inverter as a 5 KW system. As the electricity is generated by the modules this system only has a 1 kW capacity and the price offered by the vendor should be compared with other 1 KW systems and not 5 kW plants • Brands – Products from Tier I manufacturers are typically more expensive but offer much better performance and reliability • Certifications/Standards – Products that are certified and meet quality standards are more expensive • Warranties – The price of the system can depend on the warranties offered. • PV Panels – Industry standard warranty is • 10-year manufacturer warranty • 25- year performance warranty • Other systems – Inverters, mounting structures, cables, junction boxes, etc. Typically come with a 1 year manufacturer warranty which can be extended to 5 years. Takeaways • A 1 KW rooftop plant costs about Rs.0 depending on the components (exclsuive of battery costs) • A battery backup could add considerably to this cost but is not recommended unless absolutely necessary due to losses when charging or drawing power • Any further decrease in PV module prices are not likely to significantly reduce project cost as modules comprise only half the total cost of the project • Customers should check that the PV plant capacity quoted by vendor is for the module capacity and not the inverter capacity Related Posts: • • • • • • • • • •.

A solar panel is a device that converts solar energy in to electric energy. This is a series parallel connected assembly of voltaic cell and generates DC out put. This DC out put is connected to inverter and produces AC output. Its wattage rating is range from 3 W to 250W. The efficiency of the panel is very important to determine the number of panels for required voltage and current. Our power generating module is German made with the International product quality certificate like ISO 9001 certification of BSCIC and JAS-ANZ, IEC 61215 certification by Euro Test and TUV. Solar panel convert light energy from the sunrays into electricity by the means of photo voltaic effect.

Most solar panels are made up by silicon photovoltaic cell. For this crystalline silicon cells or thin film cells based on cadmium telluride or silicon are used. There are many arrays of cells. Each cell is connected together for completing circuit for a specified wattage. Connections are made by silver, copper or non-magnetized conductive materials.

Electrical connections are made up by series and parallel to get desired voltage and current. Also diodes are used to protect reverse current due to the cause of shading effect. Glass is used in front of the cell to allow light to pass through it and also protect the unit from the external damage. Solar panels are less efficient at high temperature so good ventilation is required under the panels. Now a days mirrors and lenses are used to improve the efficiency of solar panels. The solar generated DC electricity is simply flowing to inverters by converting to AC and fulfill our domestic power requirements.

There are so much type of solar panels, where the mono crystalline, thin film and polycrystalline are mainly using in the field. Download 4 Temporada Prison Break Dublado Rmvb. Flyline Solar AC power system is a unit containing solar panels, solar electronic inverter and storage batteries.

This co-ordination is depending upon the usage of wattage of a customer with the help of field engineers by inspecting the field.

Advantage of mono crystalline - is most efficient and most dependable way to produce electricity from the sun. Comparing to polycrystalline mono is 20 to 30% more efficient, because each module is made from a single silicon crystal and is more efficient than polycrystalline. The silicon crystal used in single cells must be requires a much higher purity level. Mono-crystalline solar panels are first generation solar technology and have long time durability.

It produces more electricity per square meter. In Kerala climate 1000 W Solar panels can create between 4.5 Kwh to 5 Kwh electricity per day. Flyline Polycrystalline cells:- The cost of production of polycrystalline is less than that of mono-crystalline, is very commonly used. Polycrystalline cells are constructed by the method of molten silicon is poured into a cast instead of being made into a single crystal.

This material can be synthesized easily by allowing liquid silicon to cool using a seed crystal of the desired crystal structure. High temperature chemical vapor deposition (CVD), is the other methods for crystallizing amorphous silicon to form poly silicon. In this process, silicon pieces are melted in a ceramic crucible and then formed in a graphite mold to form a block of silicon.

As the molten silicon is cooling a seed crystal of the desired crystal structure is created for formation. For this process only less silicon is required and thus manufacturing cost is reduced and that is why the efficiency is poor than Monocrystalline. Polycrystalline panels only have an efficiency of 70% to 80% compared with mono-crystalline solar panel. Flyline Thin film solar panel:- These are most advanced flexible model solar panels. We can install it in any curved or plane surface where sunlight is available.

Thin film solar panel is more efficient comparing Poly and mono crystalline cells but the main drawback is lifetime is only half time than Poly and mono Crystalline cells.
