Economical LED lighting is finally here!

Energy efficient LED LightingWe have finally arrived at point in time when LED’s are at equal or less cost of the compact fluorescent, curly bulbs.  This is a major achievement as LED’s last much longer, are again, much more efficient than compact fluorescents and contain no mercury which requires special handling when recycling.

When we started working and living with solar systems 30 years ago we had no choice but to use incandescent bulbs.  Mr. Edison’s revolutionary bulb though was eight times better at producing heat than it is at producing light.  So if you want to keep that pump house from freezing or warm those chickens you have the right bulb.  But otherwise it’s time to cycle these antiques out of your home.

When compact fluorescents arrived on the scene, we were a
ble to order these at 12 volts DC and these bulbs lasted for decades.  Then they became available at 120 volts AC, the kind of power we all use in out US homes.  Then overseas manufactures reduced the cost and quality of some compact fluorescents.  I have had feedback from too many that CF’s only last a year or so.  Bummer, as the major manufactures such as Sylvania and GE still produce CF’s with excellent lifespans.  Our local utility was even moved to purchase a cheap brand of bulbs and send them out at no cost to the consumer. Never mind that the CF’s embedded energy to produce makes them a negative even after their increased efficiency.

So long live the LED.  Maybe these will be nick named as more true “Obama Bulb” as the times, they are a changing.

Soak Up The Sun

Considering solar?  Consumer Reports addresses critical questions.

Solar Panels

Solar Panels

Does my house have to be situated in a very sunny spot?

About how much power can I expect to get?

Is it possible to save up power to use at night or on rainy, overcast, days—or during a power outage?

My area is prone to storms. Can hail and lightning damage solar panels?

Will solar panels damage my roof?

Are solar systems crazy expensive?

What about maintenance?  

What should I look for in a PV installer?

An article in the latest Consumer Reports October 2015 answers these questions and many others.

This Photovoltaic system is typical of many we install in Western Montana. Here we have 12 -235 watt solar modules which create a 2,820 watt solar array. The modules are secured with a flush mount aluminum racking structure which is tied into the rafters of the roof. Since this is a metal roof we have specialized neoprene gaskets at each penetration to assure no moisture will penetrate the roof.

A 3,000 watt Fronius grid-tied inverter is the third major component of the system. This unit receives the high voltage DC power from the array and converts it to 240 volt AC power which runs our household electrical loads and Sells any excess power back into the grid. The inverter includes circuit breakers and software which synchronizes with the utility grid and protects utility personal.

One interesting and sometimes overlooked fact is that a system such as this needs to see power from the utility grid to operate. If we have a power outage here, our system will go down even if it is good and sunny. Once the power returns the inverter waits five minutes watching for good steady power before it reenergizes.

If you are interested in having power with or without the utility, check out the battery based inverter systems. We also have a relatively new inverter option which provides a limited amount of power to a specific circuit (1,500 watts) when the grid is down and we have sufficient light to produce power.
