In Energy Tips, Solar Advice

If you have a small home, where one to three people reside, you could be perfectly content with a 2kW PV solar panel system. Not only is it likely to cover your needs from the perspective of energy generation but it also gives you those green credentials, making your home much more energy efficient and environmentally friendly.

It’s a simple task to get quotes from different suppliers and if you would like to talk to the Caldor Solar team, you can simply get in touch here. The consultation service is free and we’ll be able to give you guidance on the next steps to take when it comes to the grants and initiatives in place that are currently motivating people to make the move towards new energy solutions.

How Does A 2kW Solar System Work?

While different suppliers use different manufacturers, the fundamental principals are the same. Every system is created using a number of solar panels. A 2kW solar panel system would cost less and produce less than a larger system but the basics remain unchanged. They capture sunlight, convert it into usable electricity which can then be used to run your household goods. With a 2kW system, the output expected would be in the region of 1,487kWh/yr to 2,258kWh/yr depending on location, orientation and shading. It’s always worth you while to do your homework, get the last year’s utility bills to hand and see how much traditional energy you could offset with a solar energy system

A system of this size would require roof space of about 14m2 and would cost from Broad budget price of €4,000-€7,000* in Ireland (keeping in mind that there are a number of variables that can impact this price). It is always recommended getting three quotes, bearing in mind that you should always go with a registered, established and recommended provider. You can view our own reviews right here.

How Do I Get the Most out of My PV Solar Panels System?

What your panels generate will be dictated, to a large extent, by your geographical location, as well as the angle of your roof. An experienced installer will quickly be able to determine the best location for you and design a system that will answer your requirements. They will also look at the surrounding area to ensure shadows aren’t being cast by trees or neighbouring houses that could prevent your panels from reaching their full potential. 

You can read this blog for more information relation to the installation process.

How Long Will It Take For Panels To Pay For Themselves?

How long it takes to get your return on investment will depend on how much your system is generating, how much you paid for it and how much you’ve been spending on your bills to date. Unless the government steps in soon, it is expected that residential electricity will hit €1/kWh which, in shop talk means that your payback period is only going to get shorter.

To ensure you’re hitting the right marks to get that ROI, we strongly recommend going with an installer that is accredited correctly and goes through the processes in detail with you. If they are registered with the SEAI, it is likely you’ll be able to access grants  as well as benefit from the new feed in tariff scheme which allows you to sell any excess electricity produced back to the national grid.

If you’re looking to install a larger system, the processes and procedures will look the same, it’s the cost and electricity that is generated that will both go up. Talk to one of our team at Caldor Solar and we can shed more light on questions you may have.
