Solar Panels in a system and powerspout water turbine with MPPT controllers and Hybrid inverters from DNM Solar
We ship solar panels, off grid kits, gridtie kits, and systems across Canada
been selling solar panels since 2011
Please contact us, we would be more than happy to speak with you about implementing renewable energy solutions
We have shipped Solar panels with Inverters and batteries across Canada since 2011 any where from NL, New Brunswick, NS, PE, Montreal, Quebec, ON, MN, SK, Alberta, BC
Panels have been shipped to Toronto and including Victoria BC, Vancouver BC, Kamloops BC, Kelowna BC, edmonton AB, Calgary AB, Winnipeg MN, Prince Rupert, Nova Scotia, PEI
Earth receives a HUGE amount of solar radiation every day. About 30% of it is reflected back to space, the rest falls on clouds, land and the oceans. Solar radiation (sunlight) is used in generating electricity. Solar power is the conversion of sunlight into electricity using photovoltaics (PV), PV converts light into electric current using the photoelectric effect. Next the Direct Current (DC) that is generated by the PV panels is converted to Alternating Current (AC) by means of an inverter so it can be connected and fed back to the utility lines.
For a microFIT subscriber the generated power from the solar panels and inverter is measured by means of a standard meter and the total power generated is paid at the end of each month.
In Ontario (44 degrees) sunlight average is about 3~4 hours per day per year, that means (lets pick 3 hours), 3 x 365 = 1,095 hours of sunlight. If you have 1, 250W panel say from "Canadian Solar", that would mean 1,095h x 250W = 273,750W or 273.750KW of power in 1 year.
microFIT allows up to a one 10KW system, which means 10,000W/250=40 panels (250W each and installed on a dual axis tracker for optimum production).
Therefore 273,750W x 40= 10,950,000 W or 10.950MW of power / Year in Ontario.
MPPT vs PWM charge controllers
Is there s a difference?
Question always comes up, is MPPT better than PWM when charging with a solar panel?
Answer: A BIG YES
Here is why...
(assuming perfect conditions)
When you connect a PWM charge controller to a 250W solar panel charging a 12V battery, the controller puts out the maximum current the panel produces out, 8A in this case, but only takes 12V from the panel to charge the battery.
12V x 8A = 96W is what the controller puts out to charge the battery, while the panel is capable of 250W.
In this case the controller looks for the best power point from the 250W panel by sweeping the Voltage and Current lines from 0 to MAX and once it has found it, it starts to convert the MAX power into charging the 12V battery. 250W panel puts 30V and ~8A current out.
250W / 12V = 20A
MPPT controller will put out 12V and 20A of current into charging the battery, it takes 30V and 8A from the panel.
At $180 for a basic TS45A PWM charge controller, your charge current is 8A
At $350 for a Phocos MPPT controller your charge current is 20A
You will spend ~3 times less time to charge the battery with an MPPT controller.
You are spending less than 2 times on the MPPT controller.
You decide which one is the right controller for you.
Here is an excellent source of knowledge from the PowerSpout designers. Please take a look at what they have to offer.
"Even a small stream can generate consistent, clean, dam free, renewable electricity at a price per Watt lower than wind. A single PowerSpout at a site good enough to generate 1kW can produce enough electricity for a typical house for a year (greater than 8,000 kWh per year). The small (18 inches wide), all-weather PowerSpout PLT is one of the most reliable, cost-effective generators around because we have spent a decade making micro-hydro efficient and affordable"
What is it?
It's meant to reduce your yearly purchase from the grid
You will generate green power and use it, extra generation will go to the grid.
Your local Hydro company will store this extra power produce from the solar panels, like a battery.
You get to use the stored power for free until it runs out.
system could be sized such that your yearly need is 0KWh from the grid. You would only pay an admin fee.
Payback at current rates is about 4 years.
You will not pay, debt retirement, losses and all the other parts they add on top of your bill.
electricty cost is going up 33% in the next 3 years...
The system is identical to a microFIT setup
Solar Panels plus grid tie inverter to a secondary meter to measure and pay you.
The difference is where you connect
Solar Panels in a solar system plus grid tie inverter to your existing electrical panel to save you money.
