Deep Cycle Batteries for Solar Electric System
Author: Timothy Kolawole
Since the PV panels produce electricity whenever the sun shines on them, if the system is off-grid, you'll need a battery bank (i.e. a group of batteries wired together) to store energy so as to have electricity at night or on cloudy days. For off-grid systems, battery banks are typically sized to keep household electricity running for one to three cloudy days. Grid intertied systems can also include battery banks to provide emergency backup power during blackouts- perfect for keeping critical electric loads operating until grid power is restored
Deep cycle batteries are designed to be discharged down as much as 80% the time, and have much thicker plates. The major difference between deep cycle battery and other s that the plates are SOLID lead plates- not sponge. This gives less surface area, thus less ainstanta power like starting batteries need.
Lead-acid batteries are the most common battery used in solar electric systems. Flooded lead acid batteries are usually the least expensive, but require adding distilled water occasionally to replenish water lost during the normal charging process
Sealed Absorbent Glass Mat (AGM) batteries are sometimes called astarved electrolytica or adry', because the fiberglass mat is only 95% saturated with sulfuric acid and there is no excess liquid. They are maintenance free and designed for grid tied systems where the batteries are typically kept at a full state of charge
Gel-cell batteries can be a good choice to use in vibrated space due to their freeze-resistant qualities. They are avalve regulateda which means that a valve keep a slight positive pressure. In rechargeable batteries, this process can be repeated many times. Batteries are not 100% efficient-some energy is lost as heat and chemical reactions when discharging and charging. If you use 1000 watts from a battery, it might take 1050 or 1250 watts or more to fully charge.

It depends on too many individual things. Somewhere between $10,000 and $50,000. You need a contractor who specializes in solar systems, not one who sells heating systems. There are many around the country. Like these guys.

Here are some costs they quote:

You might try calling your State environmental office to see if they have a list.
how can I find out about how much money it would cost to convert my electric house to solar energy?
Is there a way to calculate it? what about any government agencys? when I contact local guys they just want to sell me a new heating system. thanks, any info will help!
Solar heat is radiation from the sun. It is absorbed by a surface and conducted through the surface usually metal to the water.
Electricity flows through a resistive heating element where it generates heat. The heat conducts from the element into the water.
whats the energy transformation of an electric & solar water heater?
is it solar to thermal for solar?
is it electric to mechanic to thermal for electric answers, answer, answers please.
Can the whole Philippines capable of supplying electric power coming from solar energy?
I have read an issue that about 92 Miles Sq. of Solar Could Power the USA. How many sq. km. would you think could power the whole Philippines?
Does the Electric company pay me for Solar energy?
I am moving into a house with Solar Panels that feed unused electricity into the PG&E grid.
1. Does the electric company have to pay me for giving them electricity if I use less than what my home generates?
2. Do they send me a check in the mail or credit my PG&E account?
YES…. however only a couple of states require the account balanced each month, most give you a rolling energy credit that’s balanced at the end of each year. with solar cells alone I doubt you’ll come close to break even let alone a credit and since they credit you at wholesale and charge you retail you need to be over by a lot.
I have a small solar thermal generation system using a Tesla turbine and a 30 kva generator as well as 3 VAWT (vertical axis wind turbines) each 2.5 kw and still have not received more than $100 monthly credit most of the time it’s 10 bucks. at the end of the year I still don’t get cash they issue me a stock option. Oh well more for retirement.
well
steam can run dinemo connected to it and produce some electricty, but i’m not sure what kind of heat energy source you want to use.
if you want to use Solar Energy ( the hottest source) then build a solar panel ( D.i.Y under 200 $ i guess) and do it

The Philippines is the second largest geothermal power generating country in the world after the USA. More than a third of our energy consumption is supplied by geothermals.
We also have deep-sea oil reserves in the Malampaya Oil Rim. Political disputes halted the exploration. However Natural gas reserves exists. One fifth of our consumption comes from it.
In 2005, Southeast Asia’s first wind farm was inaugurated, it is located in the Philippines. There are also various ongoing construction of wind farms in the country.
The old hydroelectrics are still operational. One fifth of our power comes from it.
Solar energy initiative was started by Marcos during the 1970s. And since then many foreign investors have installed solar farms here. I don’t have the exact figures, but I can tell you however that less than 10 percent of our consumption comes from it.
The future is renewable power supplies, coupled with alternative fuel vehicles:

How do I convert heat energy in to electric energy?
I want to somehow convert heat energy in to electric energy commercially.
I know that you can convert light energy into electric energy using solar cells… but how do you do it using heat instead of light commercially.
I say commercially as in a normal person can go out and buy solar cells and start converting energy right at home, so how do I do it with heat?
