Choosing between solar trackers and fixed solar panels mounts

When considering home solar power you will first want to: Update your appliances and get your demand down as low as possible. Convert any appliances that you are intending to convert (such as installing heat pumps to replace those that use fossil fuels).  Replace any incandescent bulbs with LEDs. Now you are ready to...

Solar heating and energy generation

Solar energy Our future truly depends on us continuing to develop and implement renewable energy systems. In Canada, Ontario is at the forefront of that movement by offering strong financial incentives for homeowners to produce their own energy. Some of the other provinces seem to be lagging behind, offering artificial...

Ten questions to ask a solar panel contractor

Diligent research is absolutely essential for any homeowner looking to install a photovoltaic (PV) solar panel system on their home. But at some point, you need to hand the reins over to a trustworthy contractor. To get to that point of trust, you need to ask questions to confirm you’re getting the best equipment and s...

Flexible PV 'solar glitter' panels coming soon

Standard solar panels are rigid, relatively heavy and fragile. A new product on the market called Microsystems Enabled Photovoltaics (MEPV) from mPower Technology may change that. The cells in these pliable sheets are made from high-efficiency silicon, and if one cell is damaged or loses power, the rest will continue t...

Using reflectors to increase the yield of solar panels

The continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations, for both residential and commercial use. Increasing the yield through reflection could make that an even more affordable energy supply option. Most of the advances in solar power production come from...

Where to place solar panels

There is a lot you can do in home construction to take advantage of the free energy provided by the sun. That can be passive solar, which is about home orientation and window design to passively heat your home, or active solar which involves mechanical solar panel systems. Solar panels can be either thermal (which tran...

Product of the month: Solar water heater with overheating protection

  Solar thermal panels in cold climates are at risk of freezing in winter, so in the North, we use a glycol mix as a heat transfer fluid. This prevents panels from freezing but introduces new problems in the summer months when they are at risk of overheating.  There are two main types of residential solar thermal heate...

Lithium-ion solar home batteries

Home battery systems have recently improved in two substantial ways, and the first big improvement is in the batteries themselves. Lithium-ion batteries on the market today are much more robust and functional than the lead-acid batteries we have relied on in the past. Discharging a lead-acid battery beyond 50% capacity...

Thermal batteries: how to passively store heat

What is a thermal battery? Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and ...

All about solar air heaters - DIY or purchased

How solar air heaters work: Solar air heater diagram © Ecohome The above diagram indicates the basic concept of a solar air heater, and while there are many designs, the basic principle is the same - a small fan feeds interior air into a south-facing wall-mounted panel. Air is heated as it passes behind a black surfa...

transparent solar panels

When considering solar cells as thin as laminate and completely transparent, the possibilities seem endless. Imagine every glass or laminant surface in our built environment and all of our devices, large and small, harvesting solar energy. In a world of passive, self-sustaining mini-power stations, would the need for f...
