Guia para instalação de painéis solares
1. Avalie se os painéis solares são adequados para a sua casa
The first step is to see if your location and home are viable for solar panels. Consider factors such as available roof space, roof direction, average annual sunlight, and incentives in your area. These will determine the system size needed and potential savings. If suitable, you can proceed to the next steps.
2. Choose between different types of solar panels
The two most common options for homes are crystalline silicon panels and thin-film panels. Silicon panels are more efficient but cost more. Consider space, location, and needs to choose panels that maximize long term savings.
3. Obtain permits and HOA approval
Before installation, get proper permits to connect to the grid, for building and safety. Check with your HOA on rules regarding solar panel aesthetics and design.
4. Select a financing option to purchase the system
There are three main options to finance panels: pay in cash, take out a loan, or do a third-party lease/power purchase agreement (PPA) to buy the electricity. Compare options to choose an affordable one with good returns.
5. Get multiple installation quotes and select an installer
Get detailed quotes from certified installers based on the size and equipment you want. Carefully compare bids considering warranty, energy production, custo, and reviews before choosing an installer to work with.
6. Plan installation and sign the contract
Work with your installer to set an installation date and plan the necessary steps including permits, removing old equipment, installing supports, inversores, wiring, and activating your system. Carefully review the contract before signing to fully understand its terms and protections.
7.Install solar panels yourself
- Purchase solar equipment and materials
You will need to purchase photovoltaic panels, inversores, charge controllers, connectors, cabos, racking systems, roof sealants or silicone, etc.. Choose high quality products that meet safety certifications.
- Prepare for the work
You will need some tools: measuring tools, wrenches, drills, electrical tools, saws, etc.. Check your roof and electrical panel to ensure suitability for a solar system. Clear the work area and turn off the power.
- Install the racks
Install roof racks or racks according to the panel specifications. Secure the racks to the roof trusses to ensure they are sturdy enough to support the panels. Qualified personnel should operate at heights. Work carefully and take appropriate fall protection measures.
- Install panels and inverters
Mount the panels on the racks and connect them to each other. Install the inverter in a cool place and connect the panel array to the inverter. Install an external heat sink if needed to increase efficiency.
- Install charge controller and batteries (if needed)
Connect the charge controller between the panels and batteries. If using batteries to store energy, connect the individual batteries together in the battery bank.
- Check electrical connections and grounding
Check all wiring to ensure correct connections. Implement proper grounding connections on the panels. Consult an electrician if unfamiliar.
- Connect the system to the electrical panel (if off-grid)
If not connecting to the grid, connect the inverter directly to the electrical panel. If connecting to the grid, obtain utility approval before connecting.
- System start-up and inspection
Check that all wiring and connections are working properly and there are no electrical faults. After starting the system, check the inverter and charge controller to ensure everything is operating normally.
8.Get inspections and utility approval to turn on system
After installation, get inspections from local agencies to ensure proper installation and meet safety standards before turning it on. Get final approval from your utility to connect to the grid. You can then start using solar energy and gaining the benefits!
9.Start using your solar energy system
Once everything is approved and connected, you can turn on your system and start powering your home with clean, renewable solar energy while reducing your dependence on the utility grid.
