To help understand the most effective methods to store energy for use on demand, this article explains what you need to know before you install a PV system on your roof.

Shopping for a solar power system and choosing a solar installer can be an exciting time for many people, but as with any investment, you’ll be needed to be careful depending on the scenario and the people you will be speaking with.
Like in any industry, the solar power sector has its share of unscrupulous parties who have little interest in the technology, environmental benefits and your needs. They are only chasing your money – and they’ll be ruthless in doing so. Basically, the old saying “if a deal sounds too good to be true, it most likely is” applies very much to purchasing a solar power system.
If your prepared to venture in buying a solar panel system, these are the factors we need to consider when deciding how to choose the right solar power system:
- Roof Size – First of all, the size of your roof will determine how many solar panels you can physically fit into the area you wish to install them. Solar installers can certainly help you by using the mapping sites Nearmap or Google Earth to measure your roof accurately. From there, you can obtain quotations for a range of sizes including the maximum allowable. Keep in mind that you can only use roof sections that face east, north and west – not south, as these will produce full capacity. Bear in mind that smaller systems can have panels facing in only one direction (multiple sections of the roof are all right), while larger systems over 3kW can have panels facing in two different directions and across multiple sections (this is a key feature of higher quality inverters with maximum power point tracking or MPPT). They can also give you some idea of how much you will look for a variety of different size options. If you’re not sure of all this, the best way is to consult with a few installers so they can assure that the solar panels you choose are the best choice for your roof and living situation.

- Budget – Determining how much you can afford to spend is a major factor that influences the size of your system. It is important to remember that solar is first and foremost a financial investment and if you calculate that the return on investment is is 15-20% per year or more, it is likely to be worth using your mortgage equity or consider financing. If you are taking this path, be careful and reduce your risk by selecting high – quality key components from a reputable installer.
- Household usage – Generally speaking, the bigger household usage, the more benefit you’ll get from choosing a larger size system. Keep in mind the anticipated growth of your family or whether you have kids just entering their teenage years as they will start consuming more energy.
