Had been thinking about installing PV panels for a number of years (having already done most of the usual energy saving things - including following my kids round, turning off lights, computers, consoles etc..), but found them far too expensive. Finally hit the sweet spot in Summer 2011 (good value installation by brilliant installer) and we haven't looked back. Just having the panels makes us more aware of how much we're consuming - and we still take it in turns to to out and admire the leccy meter going backwards!
- Make sure you're not wasting electricity first, before you invest in big ticket items.
- Get a personal recommendation if you can: how any system you're thinking of buying actually works in practice, real costs and returns etc
- Think about the long term as well as the short term benefits. With PV, for eg, even if you don't envisage staying put for the next 25 years, offering a purchaser effectiely 'free money' for the remainder of the FIT term means that you should be able to ensure that you get at least the full return of your initial investment, and you will have benefited from interim FIT payments anyway. And if you install again at your new property you're doing your bit to make Britain greener!
