Solar Panels: A Cost-Benefit Analysis
What you need to consider when calculating the value of solar panels.
Calculating a Return on Investment (ROI) for solar panels requires you to look at all the different factors that affect the cost of your solar panels and the gains provided by access to clean energy. We run through the factors that influence how much you stand to gain from solar.
1. How much do solar panel costs?
Solar panels are at their lowest ever prices, and they costs just a fraction of what they did ten or even five years ago. Prices are expected to keep falling through 2016, and there’s reason to believe that the plummet could continue to 2020 (or even beyond). Cheaper solar panels means cheaper solar energy, which is great news for those thinking of going green.
2. How much does it cost to put a solar panel on my roof?
The difficulties of taking a solar panel and mounting it on your roof account for a substantial portion of the cost of installing solar panels. That’s why it’s important to choose a company whose workmanship you can trust, and that will get the job done on time. At Complete Renewables, we offer you a workmanship guarantee of up to ten years to give you peace of mind. Remember to get any overdue work done on your roof before you have the solar panels mounted. Ground-mounted solar panels can be a cheaper option for those with the space.
3. What are the maintenance costs of solar panels?
Another major advantage of solar panels is that they have close to zero maintenance costs. This is because they have no moving parts in the system at all, meaning that there’s very little chance for a problem to develop. Solar panels are also ‘self-cleaning’ so you don’t need to worry about the accumulation of dirt either, though inspecting your solar panels from time to time isn’t a bad idea, so long as you can do so safely. We offer a ten year guarantee on your SMA inverter too, so you don’t have to worry about getting that repaired. Once you’ve figured out the costs of your solar panels, it’s time to balance those against the gains.
4. How efficient are solar panels?
Every few months, new records are broken as solar panel efficiency improves. Solar panels are a young technology, and new approaches to solar are being considered all the time. For those considering solar panels, just a few percentage points more efficiency adds up to a huge amount more energy generated over a solar panels lifetime. That’s because solar panels last so long. LG’s MonoX panels have a twenty five year lifespan, with a guaranteed 80% output by the 25th year. Getting a high quality panel is essential, as the better the quality, the more energy you are able to generate, which generously compensates for the expense of the build.
5. How do conventional energy prices affect the price of solar?
The more expensive conventional energy becomes, the more you save through your solar panels. In the short term, fossil fuels fluctuate in price wildly, but in the long term, there’s only one direction that energy prices in the UK are heading: up. Prices more than doubled between 2002 and 2012, and if they got away with it before, there’s no reason that energy companies won’t try and get away with it again. Families are noticing the squeeze as runaway energy prices have quickly outpaced any rise in wages. Solar panels are a good way to protect yourself from price hikes.
6. How does government policy factor into things?
The government has a number of policies and subsidies in place that affect all areas of energy production,including fossil fuels, and solar is no exception. Domestic home owners can benefit from the Feed-in Tariff, and the Green Deal, while business owners can take advantage of the Commercial Feed-in Tariff. These schemes provide an income for those who are generating renewable energy. The Department of Energy and Climate Change (DECC) has suggested that commercial rooftop spaces are an ideal site for solar panels, and is expected to push through legislation that will encourage growth in this area.
7. How can ‘green credentials’ benefit my business?
Now more than ever, consumers are choosing to buy products and work with companies that align with their personal values. To understand how important this is, consider the fact that ethical products, such as dolphin friendly tuna, cruelty free eggs and fairtrade bananas, have earned a space on the shelf of every supermarket in the country. Green energy and sustainability are values that the British public are adopting en masse, and no doubt will affect the companies that they choose to do business with. If you are a small business owner, you stand to gain enormous favour with ‘green’ consumers by having solar panels installed.
8. What are the environmental costs of continuing to use fossil fuels?
These days there’s a tendency to measure everything in pounds and pence, and while we shouldn’t neglect our finances, we also shouldn’t lose sight of other important markers, such as health and happiness. The scientists are in agreement: climate change is man-made and the burning of fossil fuels is a significant contributing factor. Fossil fuels seem like a great deal, but that’s only because the brunt of the costs associated with climate change won’t be shouldered by us, but by our children and our grandchildren. It’s hard to put a value on it, but by transitioning to low-carbon technologies, like solar panels, we are investing not only in our present finances, but also in the future health and happiness of the next generation.
