For the technical people who love numbers and strait to the point facts (like me!) I came across some numbers for you 😉

Sooo How much is one hour of sunlight on three square meter worth?

Let’s see, if we’re talking about electricity and we say that electricity is worth $0.10 per KWH than 3KWH’s are worth $0.30. The problem is that PV panels have a radiant energy conversion rate of about 20% or less so three hours of sunlight on one square meter of a solar panel is worth less than $0.06

How about heat?

How much is 3 hours of sunlight on one square meter of a solar collector worth if we’re talking about heat? Well 1KWH = 3400 BTU so 3KWH = 10,200 BTU.  Since one gallon of fuel oil contains 150,000 BTU 10,200 BTU’s are the equivalent of .07 gallons of fuel oil.

Now if fuel oil is selling for $2.00/gallon which it soon will be the value 10,200 BTU’s is about $0.14. You might think this is an unfair assumption since we’re not taking into account the heat conversion efficiency factor like we did with the solar panel. I’m glad to see you’re paying attention and you are right about this. The heat transfer efficiency of a solar hot water system is between 50% and 70% the same as oil burner heat transfer efficiency. Since the heat transfer efficiency for an oil burner is about the same as solar collector and the price of oil is $2.00/gallon than the value of 3 hours of sunlight on one square meter is worth actually $0.14.

How about the value of heat energy over the period of one year on a roof (20’ x 50’) tilted south at a steep pitch designed to maximize heat gain?

The surface area of the roof is 1000 sq ft or 95m2.
The solar energy available (for north central USA ) over the period one year on one square meter is 1500KWH. So on 95m2 we’d have:95×1500 or 142,500KWH or 484,500,000 BTU or the fuel oil equivalent of 3,230 gallons of #2 fuel oil. At $2.00/gallon our solar roof could save us as much as $6,460/yr. If half this energy is used for heating and half is used for electric power we could meet the residential requirements for energy independence. The question that you should now be asking is: How much would a house like this cost?

Get the point yet? Get the kit now!!

Position trees and plants to direct a cooling breeze into your house, whiles shading it during summer.

Use small trees and shrubs, the tress will provide a nice breeze and the shrubs will make shade results in cooler temps

but im no gardner, it worked for me though! before waves of heat would come in… not anymore 🙂

Vent your house

June 26, 2009

Open your windows of course BUT keep the sun from shinning in with Shutters or Solar Shades. They wil lstop the direct sun light from turning your room in to an oven.

Position doors and windows opposite each other to allow for a cooling breeze to flow through the house when the air cools down in the evening of a hot summers day.

Open doors

1. It Works! Thousands of people have successfully built their own solar energy

2. Saves Money – you save money when you don’t have to spend $thousands$ on a “retail solar system”

3. GO GREEN – reduce your carbon footprint and help the environment

4. Save Energy – you could cut your energy bills in half, or even completely eliminate them!

5. It’s Fun – just wait until your friends and family see what you have created!

Start today, get your kit!

Well in the colder season you want to keep as much heat in as possible here are some tips

  1. Make sure your walls, roof and floors are insulated and fill any gaps where draughts might come through.
  2. Make sure cracks under the doors have door sills, PLENTY of heat gets out that way
  3. Keep rooms that nobody heating vents closed along with the doors
  4. Got draft windows? Get window plastic, it makes a HUGE difference

Well im sure you think you will be search all around the work for the parts for the build? I did at first too but most are at hardware stores like Home Depot, Lowes, etc…

Start working on your panel now!

The position of you house have a big impact in the warmer seasons, move your main living area of the house to the opposite side of where the sun hits your house (if you have enough rooms of course)

When the sun hits your home it will heat on the one side more then the other just like it does the earth, its DIRECT rays of energy so DIRECT yourself to the side of the house with no DIRECT sunlight 🙂

BUT the side that has the most sun light you would be very happy of your solar panel was there

But im no Handy man!

May 22, 2009

No handy man? So… kids have made very similar kits like these in science class. You will just be taking it into another level (bigger panels lol)

I’ve been told by many people that the guide was able to take even the most difficult solar panel construction methods and distill it down to simple and easy steps that even complete beginners can easily follow.

The guide breaks it down till the point where u may feel it’s going to slow for you! You’ll get the hang of it in no time and see this is beyond simple

The sooner you get your kit? the sooner youll  be saving… Start saving now!

check back soon for saving on energy also! 🙂

Time for Solar Energy

May 17, 2009

Let’s get strait to the point times are rough right now… everyone losing jobs and no one seem to be hiring. Which leaves us to start thinking of ways to save money, why not start cutting down on your utilities?

Solar energy for homes makes the greatest use of the sun and best of all its free energy! Of course you’ll have to spend a little money to get the equipment to use the energy but trust me it will pay itself in months.

To get the ball rolling get the Do It Yourself  Step-by-step guide to making your own panel! saving easy over $1000
