The easiest fix to ensure solar projects are working at their peak is to replace inverters in a repowering situation. Solar Power World talked with Igor Mogilevski, product and solutions director for inverter manufacturer Solis, about repowering efforts and the small details one must consider before taking on this operational expense.
There is an ALTERNATIVE UTILITY CONNECTION called a “Supply or Line Side" connection. This connection is made BEFORE the main breaker. A junction box is added between the utility meter and the main service panel. Then the wires from the utility meter, the main breaker panel, and the PV solar are connected in the junction box.
A junction box is added between the utility meter and the main service panel. Then the wires from the utility meter, the main breaker panel, and the PV solar are connected in the junction box. An adequately sized PV service disconnect box must be used prior to making the connection between the junction box and the solar inverter.
Once the utility has received the approved final permit, it will schedule an inspection of the installed system. During a site visit, qualified utility personnel will test the solar system and, if necessary, replace or install revenue meters. When they approve the system, the utility will notify the account holder and the installer.
Always refer to the NEC code in effect or consult a licensed electrician for safety and accuracy. There are two basic approaches to connecting a grid-tied solar panel system, as shown in the wiring diagrams below. The most common is a "LOAD SIDE" connection, made AFTER the main breaker.
The account holder or the contractor who designs and installs the PV system may submit the application. It usually includes professional technical drawings, such as site plans and an electrical diagram. In the parallel permitting process, the AHJ will complete the inspection and, when passed, will issue a signed final permit.
The National Electric Code allows for a few different ways to interconnect PV systems to utility systems. In two editions of Code Corner, Ryan Mayfield with Mayfield Renewables, explains busbar, load side interconnections in 705.12 (B) (3) (1) and (2), and then supply side connections in 705.11 (C) and (D).

New to the NEC 2020 we have section 705.11 which helps us understand how to make supply-side connections more clearly than previous iterations. To this point, installers have been making supply-side connections in PV systems following the Code to …
I don''t think it is really called a line-side tap when it comes after the first OCP. My old place was already set up that way, a 200A main breaker and meter in one box. New …
I don''t think it is really called a line-side tap when it comes after the first OCP. My old place was already set up that way, a 200A main breaker and meter in one box. New place I''m upgrading to 200A and doing the same (200A main breaker only panel, fed by a meter box.)

Reliable Power Supply: Transmission lines are responsible for delivering electricity from power generation sources (such as coal, natural gas, nuclear, wind, or solar power plants) to distribution networks and ultimately to homes, businesses, and industries. They enable a reliable power supply by connecting different regions and ensuring a balanced load …
Solar Interconnection Methods Line Side Tap. Governing Code(s): NEC 705.12(A), 705.31. A line side tap (or supply side tap) refers to a connection between the meter and main breaker. This is the preferred method of interconnection for solar installers as it is the most straight forward and requires the least amount of calculations. However ...
Solar energy and mains power complement each other to charge the battery bank, and the energy provided by the battery bank can ensure the normal operation of the LED street lamp. The controller controls the on-off …

Fortunately, in many cases, there''s a solution other than decommissioning the old solar system and building an expensive new one. By upgrading key components to newer, more efficient models, repowering utility-scale solar projects extend their lifespan while enhancing their reliability, efficiency, performance, and ROI.
Solar produces DC (Direct Current) power and can run DC electrical devices directly without using an AC power supply. Like most electronics, LEDs naturally run from DC current and do not require an inverter or ballast to create an AC current for these fixtures. This is the most efficient way to power a solar lighting fixture or most small electronic devices such as cameras. Autonomy. …
SMA and Enphase are two companies that make special solar inverters that are designed to automatically disconnect from the grid in the event of an outage, while still providing power to your home from your solar panels. SMA Sunny Boy Secure Power Supply. While most solar inverters have that automatic shut-off we discussed above, SMA Sunny Boy ...
Solar lights are designed to gather the sun''s energy during the day and radiate it back at night, often through high-efficiency LEDs. When the sun is shining, light hits the device''s solar panels, which converts this radiant energy into electricity. The electricity is used to recharge the batteries. During the night, or a sufficiently cloudy day, the solar cells stop receiving …

Therefore, until it is significantly dark or until the solar panel is able to supply at least 0.6 V to the BC547 base, the 2N2222 remains switched off, which in turn causes the LEDs to remain shut off. Once the solar panel voltage drops below 0.6 V, the BC547 transistor slowly starts turning off, causing the 2N2222 to slowly start turning ON.
