HOW TO DETERMINE THE BEST SOLAR POWER SYSTEM FOR YOUR HOME.
Buying a home solar power system can be a very exciting experience, but don’t get too carried away by advertising. Be sure to focus on the important aspects of your purchase as it’s a substantial investment and one you’ll be living with for a long time. The following are some buying solar tips on what to look for when purchasing a system.
Ask friends, family neighbors or colleagues who have had solar PV systems installed; Often the best buying solar tips com from right in your neighborhood. They’ll be able to tell you about their experiences and perhaps alert you to any problems they experienced – ones that you’ll be able to avoid.

Length of manufacturer’s warranty
Take note of what guarantees the manufacturer offers. If the manufacturer is reputable and the warranty period on the panels is substantial (at least 25 years) you would naturally expect your solar system to last long for a long time, long enough to pay for itself and make you a profit.
Have realistic price expectations
If you are paying substantially less than many other similar size systems quoted, you may find poor quality equipment and/or poor installation work. Quality equipment and installation isn’t cheap and, like all other purchases, you often get what you pay for.
Compare components and warranty periods and check into the company providing the installation. While large, well established companies can pass on substantial savings due to increased buying power, other companies often reduce costs by cutting important corners.
Solar panel certifications
This applies to all solar panel purchases, but especially to the purchases that could attract a government rebate. The certification on solar panels indicates the type of testing that has been done on them. For instance, TUV IEC 61215 confirms that the solar panels have been tested by an independent laboratory and have met their advertised specifications. Other certification types are often self-assessed, therefore rely on the company being honest in what it claims.
Decide on the type of panels
It used to be the case that if you had limited roof space you would need highly efficient (and very expensive) mono-crystalline solar panels. This is rapidly changing with advances in poly crystalline panel technology and some thin film technologies. Still, even if you have ample roof space you may still want to consider panel sizes vs. output as filling up your roof with inefficient panels will affect your ability to add more panels at a later date, and does not maximize the power output of the space.
It’s also important to bear in mind that regardless of claim, no solar panel technology will produce a significant amount of power in full shade.
Solar panel mounting
Make sure that the roof, ground mounting or tracking system is engineer certified for the area you are in. Quality systems are wind certified; after all you do not want your system to take off during a wild storm . The mounting system is a very vital component and some suppliers skimp on this item. Make sure you ask about wind certification, warranty arrangements and get copies of relevant documents.
Solar inverter efficiency
A power inverter is the box between the panels and your appliances that converts DC electricity from solar panels to AC; suitable for use in your home.
Not all solar inverters are equal and inverter efficiency will have a direct impact on the amount of time it takes for a system to pay for itself. Look at the inverter efficiency before purchasing a system. Industry leading solar inverters for grid connect systems in Australia include SMA, Sungrow and Fronius. Be cautious of generic type brands.
It always wise to gather a few solar quotes when making a major purchase as you will find that prices vary widely between providers. They may wind up costing you more in the long run in terms of reliability and efficiency.
