How much do I need to worry about lightning? | 10 comments (10 topical)

Thanks for the reply.  I'm rural, on grid now unfortunately, just a hobby application.  I'm mounting the panels on the ground.  I figured if they weren't attached to the house & I was just charging batteries then the insurance co. shouldn't complain too much.  Not that I'm going to tell them.
Good to know I'm better of with pvc.  Lots cheaper.  Actually I guess I could just use underground wire & do away with the conduit completely.  I'm a little worried about the wires coming in to the house though.  I guess I'll just unhook them if it storms.  Probably the safest bet all around.  I've just got a couple sets of HF panels so not able to do too much right now.  So far I'm running the filters & air pumps on 2 aquariums & the better looking half's tv light (cfl).  She seems to think we should be able to do more for the money I've spent!  Maybe I'll get more appreciation when the power goes out.

I too was worried about the lightning issue. We have nice tall Oak trees that have more than once taken a hit instead of stuff around them, but never hurts to be safe.

As far as the HF panels and better 1/2, have a look over at some of the other posts on this subject :-)).
I have a few as well, and the last time power was out for the entire block, I merely went down stairs and flipped a switch, TADA lights and coffee :).

While grid is up and all, do the little things, obtain or build LED light strips, low wattage CFL amazing how much light a 7 watt CFL will put out when all others are dark.
Go to resale shop, find that neat at the time little Mr. Coffee 4-cupper, and an el-cheapo inverter that will just handle the max surge, I use a 300 watter, and when light go out, go make the coffee and the other 1/2 will think you're the cat's meow :)

Then be ready for visit from the neighbours :].

Abouve all else , Have Fun with it!!

Cheers;

I rigged up a few LED lights but they put off a funny blue colored light.  I got 3 of those HF triangle shaped LED touchlights & wired them in a series.  It works but I'd like to find something that puts out more of a white light.  Blue beats nothing when the power's out I suppose.  That is a good idea about the coffee pot.  That should score me quite a few points in certain situations.
When I have the spare cash I'd like to get more batteries.  If I could keep the TV on for several hours I would truly be a knight in shining armor.

brkwind2;
  If you're up to it, here's a link to a webiste that I buy my bulk LEDs from."http://www.hebeiltd.com.cn/?p=z.led.products.pricelist"

They have pics of what the LED light will look like when lit.
I normally go looking for their posting up on Ebay too since they posts there and can be bought in smaller batches.

The wide angle amber colored ones seem to be the better lighting for steps or floors.
The ultra-whites are good for putting a quick light in a room, plus they light up just holding them with a watch type battery :)

RS is also a good place to find LEDs to switch out those blue ones if you're up to some soldering work, I did, I use the amber ones and was much much nicer to look at.

Have Fun with it;
Bruce S

Thanks for taking the time to reply.  Good info.  I'll check it out.  If I can get decent light from LED's that would make the wife mitey happy when the power goes out.  Maybe she will get a job & buy me some more solar panels!  I can dream can't I?

The best leds (in terms of efficiency)are the Cree Q5. They put out slightly greenish light around the edges but can handle ~.3 amp (at around 3 volts) without a heatsink if mounted on a "star". I got some from Deal Extreem (China, but thought Cree was American) for about $5 each. If they are heatsinked, they can handle a whole amp. In comparison, an ordinary 20 cent led can only handle ~.02 amp. The less current, the more efficient and are far brighter than ordinary ones at the 20 mA. At 300 mA, they put out about 100 lumens which means that a glass and silicone encased set of ten 1x3 cells charging 3 sets of 3 AA Nimh will last all night long and light up an entire room enough to read by! I made mine to use less current to ensure it still stays lit on winter nights.

Thanks for the reply.  I may need a new light for my fish tank.  I might experiment with LED's there for the experience.  I had a Wally world 12v flourescent I modded into a regular fish tank light fixture but the wife said it isn't working.  Maybe I didn't do a good solder job or something.
It took me a while to figure out how to reply to you guys.  For some reason I never got the option to reply in the solar section.  I had it in other sections?  Anyway, I had to delete temp. internet files, cookies, & history & then log back in. After that it worked.  So if you reply, rest assured I'm reading & appreciating your comments even if you never hear from me again!

The not able to reply, happens once in while. No real reason why it happens.
I have two broswers and switch over when it happens.
I have less of this problem using the newest Opera.

You might want to wonder over to Commanda's posts, she's got some awesome instructions on building up LED lights , as well Rich has a post were he built ones thatre now being used in Fiji after the last trip out. These make some very good lighting!!

Cheers
