How To Build Solar Panels

100 watt solar panel

Being the cheapest system but with great benefits, many questions on solar enthusiasts lips is; what can I power with 100 watts of solar power? well, hopefully we can find the right answer for you. Read on to learn more...


Apart from being able to power a few DC gadgets and lights, a 100 watt solar panel serves charging batteries best, which can then go further on to power appliances which a 100 watt solar panel cannot solely do on its own.For example, a 100 watt solar panel will not be able to power anything over 100 watts. However, a battery can!


Now, a few things need to be factored in, in order to have a fully functional and reliable system, if being powered by a 100 watt solar panel. Things to know include:


  • (1) Power Draw
  • (2) Duration of Operation
  • (3) The amount of sunlight the panel can receive in a day


This is How Those Factors (Above) Work Together...


  • 1. The amount of power a single 100 Watt solar panel can produce needs to be calculated by the duration of sunlight it can receive in a single day... So if the amount of sunlight it receives in a day is 7 hours, then thats a total of 700 watt hours per day (Provided there's enough sunlight)... The math for that is simply: 100 watts (solar panel) x Hours of sunlight = total watt hours.
  • 2. Next the appliance you want to run must not exceed the amount of charge that the battery can receive: For example, provided the battery can receive 700 watt hours a day, then you can use the battery to run appliances that draw 100 watts for up to 7 hours or, appliances that draw 175 watts for 4 hours or appliances that draw 350 watts for 2 hours and or finally, appliances that draw 700 watts for 1 hour... You get the picture. Also, losses must be factored in so you're probably best dropping 100 watt hour from the total power...
  • 3. Next, you will need a battery that can fully charge by the total watt hours produced by the solar panel. So if you were to use up for example, 600 watts, then your solar panel must be able to supply 100 watts for at least 6 hours. get the balance right and you could power more appliances beyond the ability of the solar panels on its own!





















































A 100 watt solar panel can produce a total amount of energy governed by the amount of direct sunlight it can receive a day. For example, if a 100 watt solar panel received about 8 hours of direct sunlight in a day, then technically, that panel could potentially produce 800 watts of power a day! Now, think about storing that in a battery! You would have more than enough power to do a load of washing! We use washing machine because I think it's a perfect analogy on explanation.


So with the kind of energy system explained above, you could basically run your washing machine for free!


Now, take that knowledge and think about it on a larger scale and very soon you can see the potential on money savings! A few people have gone off the grid completely using such systems, could you imagine the savings?

Here's a simple energy system that is cheap and could power a host of appliances within your household, such as lighting for example. But this same system with inverter included could run a washing machine. But you must understand though, there are a few technicalities you'd need to understand. Firstly, anything that runs off of a motor, such as the washing machine for example, needs to be able to supply the inductive load. For example, the appliance would need about ten times the power that runs it, just to start it!

Basic 100 watt solar energy system

Resistive loads, such as incandescent lights for example will start from the power it takes to run it. Let take a look at some basic math... If you had a 100 watt inductive load, such as a motor for example, you would need an inverter that has a surge power of about 1000 watts to run it. 1000 watts would be sufficient to start it and then the 100 watts continuous will keep it running.


If you need more information on solar power, then you can find professional advice from the DIY Home Energy guide. This guide will show you the ins and outs of solar power and will even show you step by step how you could build your own solar system from relatively cheap components, which you can then use to power some household appliances.
















If you are tired of spending too much time on the internet looking for information that is unavailable, then this guide will put your mind at ease!


The guide is an excellent starting point for anybody wanting to have an in depth understanding on solar power or anyone looking to eventually going completely off the grid. The guide is not cheap for some, but it is worth its weight in gold! A Great asset for Preppers!
