To determine your ideal tilting angle, check the Global Solar Atlas by entering your location. Start framing: using nails or wood screws, connect the top of all the wood posts with the lumbers as depicted below. Lastly, protect the wood against termites and fungus with borax. On top of that, you can apply varnish or waterproof paint as you wish. Your frame is now ready to welcome your solar panels. Your solar panels are mounted on top of 2 aluminum rails.
Follow the steps below to install the railings and get them ready to welcome your panels. Slide the aluminum rails in the mounting brackets and tighten them with a screwdriver.
Your frame should look like this:. The whole operation is very easy and takes around 20 to 30 min for 6 solar panels with the help of 3 people. You will find them at the back of your panel, coming out of a small black box. Connect the solar panels in series, which means that the positive wire of one panel is connected to the negative wire of the other one.
Simply clip the male and female connectors together. Now that your solar panels are connected in series, you are left with two wires ending with male and female MC4 connectors. You need a solar extension cable with female and male MC4 connectors. Lastly, you have to ground your solar array to prevent damage from lightning. For that, get a grounding lug and a bare large copper or aluminum wire. Mount the grounding lug on your aluminum frame together with the wire. Bring the wire into the ground around 1ft deep.
Solar panels are extremely robust. They will last at least 25 years and only require light maintenance such as gentle cleaning from time to time, to keep them at their highest production level. It is also recomme nded that you inspect your solar frame every six months to assess its structural integrit y. Reduce our reliance on foreign oil and improve our national security. Produce power without using fossil fuels, which pollute the environment.
Reduce your carbon footprint. Improve the electrical grid by decentralizing power generation. Create new jobs in the photovoltaic industry. What are photovoltaic PV cells? One even formed its own licensed training institute, which shares best practices with installers across the country. The marketplace for installers is expanding in a few key areas. Residential systems have been on the rise because the general public is adopting solar faster than other sectors.
There is also increased interest from governments to install solar PV and hot water units on municipal buildings. Contracting opportunities with large commercial businesses are expanding as well. Many earth-conscious companies view it as a part of their mission to generate clean energy.
In Mexico, strong federal policy is driving installations both within government and the private sector. OMA, a publicly traded airport management services company, is looking to install dozens of solar systems across Mexico. Tell Us What You Think! The access pathway shall be located at a structurally strong location on the building capable of supporting the live load of fire fighters accessing the roof.
Exception: These requirements shall not apply to roofs with slopes of 2 units vertical in 12 units horizontal Panels and modules installed on dwellings with a single ridge shall be located in a manner that provides two, 3-foot-wide mm access pathways from the eave to the ridge on each roof slope where panels or modules are located. Exception: This requirement shall not apply to roofs with slopes of 2 units vertical in 12 units horizontal Panels and modules installed on dwellings with roof hips or valleys shall not be located less than 18 inches mm from a hip or valley where panels or modules are to be placed on both sides of a hip or valley.
Where panels are to be located on one side only of a hip or valley that is of equal length, the inch mm clearance does not apply. These requirements shall not apply to roofs with slopes of 2 units vertical in 12 units horizontal Panels and modules installed on dwellings shall not be located less than 3 feet mm below the roof ridge to allow for fire department smoke ventilation operations.
Exception: Where an alternative ventilation method approved by the code official has been provided or where the code official has determined that vertical ventilation techniques will not be employed, clearance from the roof ridge is not required.
Rooftop-mounted photovoltaic panels or modules photovoltaic panel systems shall be designed and installed in accordance with this section , Section R and NFPA Rooftop-mounted photovoltaic panels or modules shall have the same fire classification as the roof assembly required in Section R The fire classification of any rooftop - mounted photovoltaic panels or modules must have the same fire classification as required by the IRC for the roof assembly itself R Rooftop-mounted photovoltaic panels or modules shall be installed in accordance with the manufacturer's instructions.
Rooftop-mounted photovoltaic panels and modules shall be listed and labeled in accordance with UL and shall be installed in accordance with the manufacturer's printed instructions. The installation of photovoltaic panel systems that are mounted on or above the roof covering shall comply with this section, Section R and NFPA Construction or work is to remain accessible and exposed for inspection purposes until approved.
Required inspections include footings and the foundation, framing and rough-in work, plumbing rough-in, mechanical rough-in, and final inspection. Per the IRC, Section R Inspections , for onsite construction, from time to time the building official, upon notification from the permit holder or his agent, can make or cause to be made any necessary inspections.
Further details are provided for inspections regarding foundation, plumbing, mechanical, gas and electrical, floodplain, frame and masonry, and final inspection. Any additional inspections are at the discretion of the building official. This section provides details for inspecting to the specific provisions for design and installation of photovoltaic systems where one or more specific types of inspection called for by the IECC or IRC may be necessary to confirm compliance.
Plan Review. Construction documents should include: Design, size, and location System ratings, testing, and labeling Conduit, wiring, and electrical layout design Mounting specifications Inverter location and listing. Portions of roof structures covered with photovoltaic panel systems shall be designed for the following load cases: Dead load including photovoltaic panel weight plus snow load in accordance with Table R
