Should you’re coping with frequent energy cuts or need to decrease your month-to-month electrical energy payments, putting in photo voltaic panels in your roof is a good answer. However how do you go about it? This information will stroll you thru the method of putting in photo voltaic panels, the instruments you’ll want, and do it safely.
Step 1: Collect the Photo voltaic System Parts
First, examine the set up space in your roof. You may need to make sure the panels can face south, the rooftop is robust sufficient, and there’s room for wiring and cleansing. If every part checks out, it’s time to collect the mandatory photo voltaic merchandise like PV modules (the panels themselves), an inverter, batteries (if wanted), and different steadiness of system (BoS) supplies.

| 12 | Cable Tray | ✘ | ✓ | ✓ |
| 13 | PVC Pipe | ✓ | ✓ | ✓ |
| 14 | Civil Supplies | ✓ | ✓ | ✓ |
Step 2: Transfer Supplies to the Rooftop
Subsequent, fastidiously transfer the photo voltaic panels and different supplies to the roof. A single photo voltaic panel can weigh round 32 kg, so deal with it with care to keep away from harm. Should you’re putting in a small system, you need to use manpower to carry the panels. For bigger initiatives, you may want tools like a series pulley system.
Step 3: Set up the Mounting Construction
Whereas some staff members carry the supplies, others can begin organising the mounting construction. Be certain that the back and front legs are accurately positioned, with the small leg on the entrance and the big leg on the again. Use M10 fasteners to safe the construction to the roof.
Step 4: Connect the Photo voltaic Panels
As soon as the mounting construction is in place, fastidiously connect the photo voltaic panels utilizing nuts and bolts. Guarantee every panel is securely fixed to the construction.
Step 5: Set up the Inverter
After the panels are in place, set up the photo voltaic inverter, which converts the photo voltaic vitality into electrical energy on your house. The inverter needs to be positioned in a sheltered space away from direct daylight and rain, at a peak of about 5 to six ft from the bottom.
Step 6: Set up the Battery (If Wanted)
Should you’re organising an off-grid or hybrid system, you’ll want to put in a battery. For grid-connected techniques, a battery isn’t required. When you have a lead-acid battery, you’ll join it in sequence, however for lithium batteries, this isn’t needed.
Step 7: Set up DCDB & ACDB
Set up the DC Distribution Field (DCDB) and AC Distribution Field (ACDB) close to the inverter. These containers assist handle the circulation of electrical energy between your panels, inverter, and residential. Place the DCDB to the left and the ACDB to the best of the inverter, about 1.5 ft aside.
Step 8: Set up the Lightning Arrester & Earthing Equipment
A lightning arrester and earthing equipment are important for security. These parts defend your system from lightning strikes and guarantee every part is grounded. For grid-connected techniques, you’ll want three separate earthing setups: one for the DCDB, one for the inverter and ACDB, and one for the lightning arrester.
Step 9: Full the Wiring
With the bodily set up completed, it’s time to attach the wiring. This step needs to be dealt with by an professional because it includes connecting varied wires from the photo voltaic panels, authorities electrical energy board, and your own home’s load. Guarantee all connections are safe.
Step 10: Take a look at the System
Lastly, take a look at the system to make sure every part is working correctly. For an on-grid system, this includes checking the connection to the electrical energy meter. For off-grid or hybrid techniques, you’ll additionally want to check the load distribution. After testing, clear up the rooftop and inverter space.
Instruments You’ll Want
To put in a rooftop photo voltaic system, you’ll want varied instruments, together with wrenches, drills, fasteners, and security gear. Be sure to have every part available earlier than beginning the set up.
