This is my 1st video interview with John Shaw Project Engineer Bella Energy of out of Louisville Colorado. Anderson Hoke Project Engineer is also interviewed in this clip.
SolarDave: Installing solar panels on a tile roof can be tricky, what is your approach ?
John Shaw: The easiest way to do PV on a tile roof weather that is curved Spanish tile or flat concrete tiles is to use building integrated PV product. Sharp has a product, Open Energy has a product, both of them basically hang on the battens. They are silicon cells so they are not the thin film amorphous that simply means that they are as efficient as a standard panel from Sharp or Evergreen or what not.
They get screwed in to the roof decking just like the concrete tiles. They intergrate with the concrete tile with a lip, this perticular one made by Open Energy is a 35 watt tile, it replaces 3 concrete tiles and it is basically the same height as a concrete tile and the width of them is the same and it is really the easiest way to do solar on a curved spanish tile or flat concrete tile roof.
If one wants to do standard tiles, there is a couple of ways to do it – the most laborious way would be to remove all the tile and and fasten to the beam.
But the way Sharp suggests that we do it is basically retrofiting so we back out just the tiles necessary where we need to make our attachments.
Anderson Hoke: You can pull one or two or 4 tiles right where you need to make the connection. You can pull out just a few tiles but at that point you can either install a standoff you want a longer one than this and flash around it, the tile institute would like to see flashing at the level of the under lament. That is interwoven with the lament and another flashing at the tiles – double flashed, that is the way any type of pipe is supposed to be flashed coming from tile but actually the way Sharp suggested you do it one of the leading manufacturers of PV is to drill a hole in the tile and they have a product fits through the roof – drill a hole in the tile and put the tile back down over their product and they have a combination of chalking and buel tape (?) method they use to seal the hole. And you can mount your PV on top of that, some really don’t like that method but that is what Sharp is recommending.
John Shaw: Specific to that type of installation so basically retrofiting over a tile roof is that it is rather laboriousin Colorado where we have to deal with 90 to 136 MPH winds so we typically need more attachements than other parts of the country.
For a 4 kilowatt system that might cover 350 sq ft we might have 36 attachments so that means 36 different points on the roof where we need to remove one to 4 tiles locate the rafter drill the tile replace the tile chalk buelded (?) etc, long story short Sharp tells us that in at least in California we need to be collecting about $2 more per watt and considering that the price in Colorado for standard efficiency panels is about $7.50 a watt all inclusive including tax, you are looking at increasing it from $7.50 to $9.50 and that is more than 20%.

I know they have solar panels and they can be bought. But, does anyone know of an example of a residential or small business in new york city that uses solar power to offset some of the electrical bills.
Will con edison allow it?
the answer to this question is what i would like to implement in NYC

Most all public utilities allow you to grid tie a solar electric system. Just how much will they pay you per kWh is the question.
It looks like NY has a lot of incentives, Check out this link to find out what the incentives are in your state.

Total the kill a watt hours for the last 12 months from your electric bills. You would normally divide that by 365 days and you have your daily avg usage. You divide that by the peak sun hours in your area and that is about how many watts in solar modules you need. Pick an inverter to match and hook it up.
You could go to the following link and spend about 15 minutes and size and price a solar kit system. I installed a 1000 watt system and the only thing missing was the electrician and the long wire runs from the roof to the inverter breaker. http://www.oynot.com/grid-tie-only-how-to.html Took about 10 hours and 5 of them the electrician was helping so it is a two person job.
Cost me 500 bucks to the electrician to pull the permits connect the wires and hand me the solar modules on the roof. I did the rest.
What does that question have to do with Reptiles ? JERK OFF !
I want to make solar powered fountain for my husband’s birthday. However, we do not get enough direct sun all day to power a "direct sunlight" solar panel. I would like to use a solar fountain pump and add a battery system to it so that the battery will charge and accomodate for periods of shade during the day. (Kind of like how solar garden lights power up all day and then run at night.)
I’ve seen systems and kits you can buy, but they seem ridiculously expensive and I’m sure this can’t be that difficult to do. Can anyone help me out w/ a How To?
I do have a basic understanding of electrical theory and wiring, but I am not an engineer, so please try to keep it simple. (I know about wiring, watts, volts, amps… I can install outlets, fix lights and understand balancing an electrical system to make sure the source is providing enough power and that the lamp won’t blow up, etc…. to give you an idea of where I am coming from.)
Thanks!
How many amps will you need to power the pump, and how many amps of power will you get from your solar cells is the real question you need to know.
Go to Radio Shack, maybe they can help you, a lot of hobbyists get electrical supplies there
i live around there, no tall buildings around or anything. i was wondering if anybody has a house that has solar panels and if it works well and how much power it gives off. specs like that.
The amount of electricity your house could produce depends on the roof square footage thats facing the sun or that can have stands to angle the panels. Many people go for a system that gives them about half of their total usage. The actual amount per square foot can vary slightly depending on the pannels you get there are amorphous and crystaline as well as different formulations of the solar material. The best bet would be to contact a solar installer in your area for a free evaluation or for a quick look you can check out manufacturers websites like sharpsolar, bpsolar and I believe home depot also installs solar now.

The term solar panel may refer either to a photovoltaic array, a collection of solar cells used to generate electricity, or to a flat solar thermal collector, such as a solar hot water panel, used to generate solar hot water or otherwise collect solar thermal energy. In both cases, the panels are typically flat, and a few meters in height and width, and are ideally sized for easy installation, and are priced so that they find typical use in domestic or light industrial applications.
Solar thermal panels are more economically viable at the moment than solar photovoltaic panels. Recently there has been a resurgence in development towards large scale energy production in parts of the world with significantly high insolation levels; solar panels are the primary component of most small-scale solar power generating facilities. Larger facilities, such as solar power plants typically contain an array of concentrators and steam turbines.
