Nearly 20 years ago I became a solar power engineer in one of the UK's most imaginative renewable energy companies. Major companies and development organisations have put their trust in me to design, manufacture and install solar power systems all around the world. There are many solar power books currently on the market, but I hope you'll agree that none of them are backed up by the wealth of knowledge and experience contained in the Solar Power Design Manual. Download it today - you won't be disappointed. In case you're not sure, I'm going to throw in the Solar Sizing Excel? spreadsheet template as well. I wrote this for myself, to save me having to do all the calculations manually, and it includes a couple of worked examples to show what's possible. I think you'll find it extremely helpful. Plus, once you've downloaded the manual and extras, you will be given the option to receive future updates, free. Remember, there's nothing to lose. If for any reason you don't like the Solar Power Design Manual, I'll give you a full refund within 60 days, no questions asked. Why wait? Buy now! Energy Efficiency Energy efficiency saves you money. Where solar energy is concerned it saves even more money. These pages will get you to think about how much energy you use. Whether it's solar energy or not, you can reduce what you pay for electricity. Energy Optimisation What do you think of when you hear about energy efficiency? Saving electricity of course. That's an important thing, but it's just as important to use the best energy source for each purpose. This is especially important if your electricity is generated by solar energy. What's the right energy source? Well it depends on two things; what is needed and what's available. For example, if you have a source of logs then that might be the best energy source for heating your living room. Before you think about which appliances or fittings you need, you need to pay attention to your energy usage patterns. Are you the sort of person who leaves the light on when you're out of a room? Do you leave the outside light on in daytime? Do you really need a huge upright freezer - if you eat all the stuff that's been in there for ages wouldn't a small chest freezer be adequate? Making simple changes to your lifestyle can be amongst the most effective energy saving strategies of all - and they needn't cost you a penny. Appropriate Energy The biggest gains are usually to be found in lighting. Using the right sort of lamps in the right places can pay dividends for anybody, but especially for solar energy users. Click here to select the right sort of lights for you. Think about what you use for heating. Not just for space heating, but cooking and water heating as well. Solar power may be no use for heating, but you may find that solar energy could help. Find out more about heating here. Refrigeration and other appliances need to be carefully considered to reduce energy use. It stands to reason that the fewer appliances you have the less energy you will use, but if there's something you have to have, then a little thought can make all the difference. Now you understand all about energy efficiency, you can start to design your solar power system.
