Are the Initial Residential Solar Energy Cost Really Worth It?
A lot of people today are on the fence as to whether or not they want to make the switch to solar electricity. Well if you're one of those people, you will find several diverse things that you are going to have to consider. First and foremost you're possibly wondering if the common residential solar energy cost is even going to be worth it, and if that's the case, the answer is always yes.
It doesn't matter who you are and wherever you live, should you make the change to photo voltaic energy, you are going to be saving big bucks in the end of it all.
Small savings in residential solar energy cost
You must understand that photo voltaic energy is limitless and free, therefore it will in no way run out and you'll never have to pay for it. Think of how frequently you must stop to fill up the tank of fuel in your car, you would never have to worry about this again in case you had been driving a solar powered car.
In the event that you've a garden or even merely a pathway to your house that you simply would like to have lit, think about getting pv powered equipment and lighting instead. You'll receive considerable solar power cost savings just from doing this alone, and you also don't need that much light in these locations anyhow.

QUESTION:
solar enertech or suntech solar panels?
what to you feel about these two? which one will get the best performance or will be more effective on same condition?
thanks-
ANSWER:
How does your wallet feel about them?The brand is not so important as the panel itself. Monocrystaline, polymorphic, amorphic, polycrystaline, are more important to consider for best performance for your area. It is not uncommon for the panels to be made under contract by someone else and branded with a name. It is not impossible to potentially have the same panel with 2 different prices that just happened to be made by the same company originally.
And the substrate is a consideration as well- where are you going to put them, and might there be a better option if you look at what options you have available to you. Say actual standing seam steel roofing versus roof mounted panels?
There is no single absolute answer that remains true in every situation. It is easy to overthink these things, but when you come right down to it- who is still going to be in business at the end of the warranty period if you are reliant upon the warranty? What were the expected failure rates of the design, and when did they normally occur during testing?
And how much can you afford as a home owner? As a business owner? As a venture capitalist? The answer will not always be the same for each of these.
For a roofing material, thin fim types are the better performers on homes- the thin film is adding only marginally to the weight of the standing seam steel, and they will still produce power in cloudy weather. They have an advantage when it comes to the design of the roof because wind loading and weight are not issues beyond that of just the roofing materials.
Monocrystalines will produce most power per foot, and will have a lesser reduction in output in hot weather, or hot roof conditions. than the other types. If you are in the desert- this type is most often going to be a top choice.
Polycrystalines are least expensive, which wins with a lot of people.

QUESTION:
Can a Solectria PVI 3000 inverter be used as a grid intertie?
I just had a grid-tie solar pv system installed with 12 Suntech panels (205kw) and a Solectria PVI 3000 inverter. My installer does not work with batteries, but knew that I would want to add battery backup.Someone just told me that the Solectria is grid-tie only, ie, does not have the capability to use power from batteries. This person told me I would have to replace the Solectria inverter. Is this true? I can't believe that the company that installed my system would give me an inverter that is grid-tie only, even when they knew I would add battery backup to the system.
Is there a way that I can add battery backup without replacing the Solectria? Any cost or other drawbacks of doing this, provided it is possible?
Thanks for any help!

ANSWER:
You absolutely can add the batteries. You just need to install the batteries and charge controller between the panels and the inverter. The inverter will use the DC voltage from the batteries the same way it uses the DC voltage from the panels.The following is just my personal opinion.
Unless you have frequent power outages the money spend on batteries and the power lost through heat while "pumping" electricity in and out of the batteries would really take away from the efficiency of the system. You also may be able to talk to your power company and check into time of use billing. They will charge you a higher rate during the day and an extremely low rate at night. Your solar will provide most of your day time needs, so you will mostly use power from the grid only at night when the rates are cheap.
