Buying a home solar system can be a very interesting but not very engaged with advertising – do not forget to focus on important aspects of your purchase, because there is a great investment and live long. Here are some tips on what you consider buying a system.

Recommendations

Ask friends, neighbors or coworkers of the family who have installed solar PV systems, but it will be able to talk about their experiences and can warn of problems – you’ll be able to avoid. More information about potential problems in our consumer guide to solar energy – avoiding the tricks and traps.

Duration of the manufacturer’s warranty

Take note that the guarantees offered by the manufacturer. If the manufacturer is reputable and the warranty on the panels is significant (at least 25 years) is likely to keep the time of the solar system long enough to pay for itself and make a profit.

Not to worry too much about the efficiency rating

This is not a simple concept when it comes to solar systems. Efficiency is a concept somewhat exaggerated, as the energy source, the light is free, and most people in Australia has more space on the roof which can be filled with solar panels. Few reviews of the effectiveness of the panel, a 120-watt solar produce 120 watts. Make sure your roof facing north is large enough to accommodate your system. Allow approximately 8m ² of land area covered by each one kilowatt solar panel

Have realistic expectations of prices

If you pay less than many other systems of similar size city, you will find equipment of poor quality and / or improper installation. Quality equipment and installation is not cheap and, like all other purchases, you often get what you pay for. Compare the components and warranty periods and check with the company responsible for the installation. While larger, more established companies can pass on savings due to increased purchasing power, other companies often cut costs by reducing key dimensions.

certification of solar panels

This applies to all purchases of solar panels, but most of all purchases that could attract a rebate from the government. The certification on solar panels indicates the type of tests that have been made in them. For example, TUV IEC 61215 confirms that the solar panels have been tested by an independent laboratory and have complied with their conditions of advertising. Other forms of certification are often self-evaluation.

Determine the type of panels

If you have limited space solar roof panels have high performance single crystal. If you have plenty of space, still may the roof, you consider using the most efficient panels ceiling panels that address the effect ineffective your ability to add more panels at a later date, not to maximize output space. If you have partial shade from thin film amorphous solar panels may be more appropriate. No solar panels will produce a significant amount of energy in the complete darkness, and who also said not to be honest with you. More vs. thin monocrystalline panels.

The solar panel assembly

Make sure roof, editing or monitoring of land certificate systems engineer for the area where you For example, if you live in an area prone to cyclones ensure that the mounting system and mounting brackets are also cyclone par. Certified quality systems are wind, after all, I do not want your system off during a wild storm. The mounting system is very important and some providers to skimp on this. Be sure to ask questions about the certification of wind, security agreements and obtain copies of relevant documents.

Choose an effective investor

An investor is the area between the panels and the equipment that converts DC power from solar panels into alternating current, can be used in your home. The efficiencies of the investor will have a direct impact on the amount of time it takes for a system to pay for itself. Look at the effectiveness of the UPS before buying a system. Obviously, the most effective investor the best – that their energy is not wasted in the process of translation. Industry Investors prefer to connect the network systems in Australia are SMA, Fronius and Latronics. Keep away from the exotic “and the generic brands.

Get some quotes

It is always wise to get some quotes to make a major purchase, you will find that prices vary considerably between suppliers, not just go down and price components can be used to reduce the initial cost of the system – but can end up costing you more in the long term in terms of reliability and efficiency.

Avoid high pressure salesmen

If someone is home for over an hour and spent more time talking about the system, rather than the study of his house, the seller is probably trying to soften at a high price. Try not to take decisions on the ground, simply ask the person to whom you can review the offer. If he is as good as they say, will remain a good morning. Asked about the spot decisions often prove less advantageous for the analysis.
