Home Solar Power System Batteries
There are a few different types of batteries, but which one is best for solar power? By the end of this article, you will know the answer. If you are planning to install a solar power system and you want to use electricity when the sun isn’t shining, you’ll require a way to store the power generated when the sun is shining. Batteries, when used in combination with with a solar charge controller, will store electricity while it is being generated by the solar panels and then let you make use of the stored energy later. So, let’s talk about the different kinds of batteries and which type is best for solar.
The first question you might have is about the newer battery technologies used in hybrid cars or laptops or ipods. There are reasons these batteries are a good fit for those devices, but as you’ll see they don’t apply to solar power systems.
These types of batteries are much smaller and weigh significantly less than older battery types. These newer battery technologies, though, cost a great deal more than the older technologies for the same capacity. For devices like ipods, being small and light are more important than cost, so these newer technologies are a good fit in these devices.
Your solar power system, though, isn’t going to move around. On the other hand, you are going to want as much capacity as you can afford. For this reason, cost per amp/hour of capacity is a lot more critical than being small or light.
When it comes to best cost for capacity, the king of battery technology is plain old sealed lead acid batteries. That’s right, the same kind of battery that is in your car. The newer types of batteries are going to cost you between 2 and 4 times what sealed lead acid batteries will for the same capacity. Sealed lead acid batteries are rugged, cheap and safe.
12 volt sealed lead acid batteries are the typically used. 12, 24 or 48 volts are the most common voltages for solar systems. By wiring together 12 volt batteries in series, you can generate any of these voltages. By then putting these groups of batteries together in parallel, you can increase the total amount of power you are able to store and the number of appliances you can power.
A 12 volt solar battery charger will use the electricity generated by the solar panels to keep the batteries charged. The charge controller lowers the amount of power applied to the batteries as they get more charged to prevent overcharging.
A power inverter will allow you to supply power to appliances you would normally plug into the wall . If you’re looking to sell extra power back to the electric company, you should use a grid tie inverter. If you don’t care about tying into the grid, or plan to live entirely off grid, a regular power inverter will work just fine and will also cost less than a grid tie inverter.
That’s the whole story. While the newer, high efficiency technology is best for solar panels, old fashioned technology is best when it comes to batteries for a home solar power system. Sealed lead acid batteries are the best choice for home solar power systems.
How long would it last battery on power inverter?
I have a trip coming up and the vehicle I'm using does not have a 12 volt plug and I cannot plug into the vehicles batteries (company vehicle).
I have an 800 watt power inverter that I plan on using connected to at least one 12V 7AH battery. I will be powering a laptop with a power consumption from 85-100 watts. My question is: how long will 1 battery last on a 100 watt draw.
They are valve regulated sealed lead acid batteries with a 13.3-13.5 volt output. I can have up to 6 of these batteries in parallel. I can't take a car battery or deep cycle battery with me.
What link for the fuel cell?
Your actual load is 100W...
With no losses the current is 100W/12V = 8.33A
This means you need 8.33Ah capacity for each hour of running, with provisos as below.
WIth a 7Ah battery that implies 8.33A/7Ah = 0.84 hours
The nominal voltage of a 12V battery is 12.6V, but you will be lucky to have 12V at the inverter terminals.
Battery ratings..
The battery will be rated at the 10 or even 20 hour rate, so that is a current of 0.7A or 0.35A for a 7Ah battery. The current you are drawing is 10 times that, in reality too much for this battery. The battery capacity is derated considerably, so the implied 100W running time of 50 minutes becomes maybe less than half an hour.
In practice the losses due to the inverter must be added as part of the load. As this is a low load for an 800W inverter it would just be a stab in the dark to say what its losses are, unless you can measure the actual current drawn from the battery when running under that load. My feeling anything from a few watts to 150W losses. It could more than double the load. You could be down to 10 minutes if the battery doesn't get overheated. Batteries are also less capable in cold conditions. A 7Ah battery is more suitable for loads about 10W.
Get the drift? You need a larger battery. The load is more consistent with an 80Ah size deep cycle battery. This would run more like expected, up to 9h, perhaps somewhat less due to inverter losses.
If you want to run the Laptop only, it makes more sense to use an external battery pack that plugs in more directly. This will be more efficient at least. Most laptops run from an 18V battery. Look into the solutions for converting 12V to 18V (Laptop car adaptors), that will run on your battery as well. A solution that might be available, or soon will be, is a fuel cell for laptops. See the link. We are talking about something like 200ml of Methanol for 20h for a notebook. Sounds attractive.
Onyx Unveils All-In-One 330 Watt Plug and Play Solar Panels (Inhabitat)
Onyx just announced that they have installed their first 330-Watt
“Plug-N-Play” solar panels at their demonstration site in Orlando, Florida.
The two all-in-one solar panels have an incorporated micro inverter and a
standard US AC power outlet plug that allows the owner to simply plug an
extension cord into the panel and then use that [...]
