3 things to remember when installing rooftop solar panels
Installing solar panels can be the best investment you ever make, and being mindful of a few key aspects will make investing in solar a trouble-free experience.
1. Choose a reputable company
The Australian solar industry has undergone many peaks and valleys over the last few decades. Companies that are dedicated to providing renewable energy solutions have weathered many storms. By contrast, those looking to earn a fast profit tend to disappear from the landscape just as quickly as they arrive, leaving their customers high and dry if the system encounters issues and requires maintenance.
A proven track record is the best indicator that a solar company will still be in business should you encounter any problems with your solar power system, keeping in mind that systems can take a few years to pay for themselves. Trusting a solar company that provides their customers with detailed information regarding the expected output of the solar system, payback period and all relevant warranty information will be beneficial.
2. Buy a system that meets your needs
Larger solar systems are justified by increased electricity consumption. Beyond simply installing solar panels and an inverter on your home, you should feel comfortable that your consultant has provided an appropriate solution that meets your needs.
Energy usage and suitable roof space affect the sizing of a solar system. When a company tries to sell you a 5kW system simply because the available roof space allows for it, or the company is offering a discounted price on larger systems it could be an indication that you are spending more upfront than necessary and over-producing. This meaning a high percentage of your solar power will be fed back into the grid rather than helping you reduce your bills.
3. Installation orientation and tilt
As the solar community becomes more educated on installation issues it has become common knowledge that solar panels are most efficient when installed on the north-facing aspect of a rooftop (in the southern hemisphere at least). If your north roof is small, shaded or unsuitable for any reason the west-facing roof is usually the next most efficient option.
When installing solar panels on a flat roof it is advisable that the panels be tilted up to maximise their exposure to the sun. Experienced solar system designers will suggest this without hesitation because they know from experience that tilt frames deliver added value well beyond the extra expense.
Being wary of these three simple aspects when purchasing solar panels will ensure you get the most from your new solar purchase.
