Going green has many advantages. The obvious one is that it decreases ones carbon footprint, in turn saving the atmosphere. Another reason to unplug from the grid is to decrease power bills. By using suntech solar panels or wind turbines, one could run ones home using natures resources. Anyway, these system come at affordable price.
What do you require to make your own solar power system?
A solar powered setup needs costly solar panels. First of all, it needs an inverter to change the power from DC to AC in order to run the appliances. Secondly, a batter pack is required to store the collected power. More sophisticated system contain solar tracking and Maximum power point trackers.
A full residential solar system installation, sized between 3 -8 kW, can cost between $15,000 and $42,000. So until the price of this technology plummets in the future, what we can perform to cut the costs of a solar system is to build our own.
Some DIY enthusiasts advise sourcing materials that match your needs and fitting it all combine yourself. This does not just save money on materials used, as there is no markup from the contractor, but also cuts down on installation and wiring costs.
DIY solar panel for producing electricity
Making your own solar panel is a time-wasting process and need s some electrical expertise. Anyway, it can also be extremely rewarding – learning to build your own PV panel is a remarkable way to understand how solar power is generated.
Before you can build your own residential solar panels, your first need to understand how solar cells produce electricity. The big majority of solar panels in use today are made of crystalline silicon wafers, which typically measure 6 inches square. When the sun shines on those wafers, the electrons in them begin to move. This flow of electrons is a power current.
A one full-sized solar panel, like the type used in a rooftop solar power systems, will have sixty silicon wafers. You can also make little panels if your power needs are low. Once you are have bought individual solar cells, the general process for building your own solar panel goes like this:
Prepare the backing for your panel. Many DIY suntech solar panel builders use a wooden board as the base for their solar cells. You will need to drill holes in the board so that wires for each cells can go through.
Wire your solar cells combine. This needs some experience with power work. Use a soldering iron to link wire to the solar cells and then attach each of the cells combine.
Attach cells to your backing. If easy, affix each solar cell to the backing individually. This makes it simpler to change a single cell in the event that becomes destroyed or is not operating rightly.
At this point you have a working solar panel that can generate electricity when the sun shines. Anyway, a solar panel by itself is not helpful. If you are trying to produce electricity to power gadgets into your house, you need to pair your panel with an inverter that will turn DC power from the sun into the AC power used in most latest electronic devices.
For a standalone off-grid system, you will also need to add a battery pack and charge controller in your DIY solar setup. The battery pack serves to save excess power, and the charge controller manages the amount of power that flows via the battery.
If you want to build a residential solar panel system that will power your house, the process is significantly more hard. A standard grid-linked solar PV system that can power your house will have around twenty solar panels, each of which will need to be wired combine and mounted to your roof. Most vitally, a professional electrician has to confirm your system has been built rightly before your utility will permit you to link your panels to the electric grid.
Advantages of solar system installation
The big benefit of installing DIY solar panels is cost saving. Generally it is possible to buy solar panel kits, using reasonable standard equipment for approximately $2.00 per watt. When this is matched to the average cost of solar panels installed by solar firms of around $4.00 per watt this can be a saving of $10,000 on an average five kW residential solar power system.
Anyway, you are going to have to pay a qualified contractor to install the system and much of this savings may go to them. Because most experienced and licensed solar electricians work for solar firms they will often charge quite a lot for installation because they see they have lost the capability to make any margin on equipment. This may charge over time but presently this is a huge factor in why it is very hard to save much money from a DIY solar project.
A licensed electrician will normally charge you $3,000 install your solar panels and so this would decrease you cost savings quite a bit.
So after installation we are possibly down to a savings of $5,000 by doing a DIY install of your solar panels for an average sized home. Anyway, this is before the thirty percent solar tax credits comes into play.
The savings is decreased by the valve of this credit and so net you are likely to save in the range of $2,000 to $5,000 by organizing installation of solar panels for your house yourself.
Disadvantages of installing DIY solar panels
- It needs a lot more research, job and effort on your part.
- You are on your own if there is even a fault within the tool and where this occurs it is possible that mistakes you have made in the installation may void warranties. Definitely, you would still have recourse to the producer but it may be hard to prove a warranty fault.
- Installing DIY solar panels is potentially serious from a number of perspectives depending on whether you are physically installing them yourself or hiring a solar contractor to do it. The installation itself can potentially be serious if you are not used to working at heights or with DC power and there can be ongoing danger of fire if the electrical work is not performed by a qualified and experienced solar electrician.
- A licensed contractor may be needed to claim solar incentives.
