SEEKING ADVICE LOW VOLTAGE VS. HIGH VOLTAGE ...

Measure the open circuit voltage of the photovoltaic panel
Read the voltage on your multimeter and compare it to the open circuit voltage (Voc) listed on the back of your panel. If your voltage reading is negative, reverse the probes and measure again. [pdf]
Photovoltaic panel shade current and voltage
When a solar panel is equally shaded, the amount of light it is receiving is very low. This does not always reflect on its voltage, but it directly affects the current.. When a solar panel is equally shaded, the amount of light it is receiving is very low. This does not always reflect on its voltage, but it directly affects the current.. The shaded spot on one panel will decrease the string of panels to 3 amps at 52.5 volts. [pdf]
Will connecting photovoltaic panels in parallel increase voltage
When connecting solar panels together in parallel, the total voltage output remains the same as it would for a single panel, but the output current becomes the sum of the amperage of each panel. [pdf][FAQS about Will connecting photovoltaic panels in parallel increase voltage ]

Reasons for low photovoltaic panel current
Reasons For Low Short Circuit Current in Solar PanelEnvironmental Factor The most common reason low short circuit current issues happen is when your panel doesn’t get the proper amount of light. . Solar Panel Problems If your orientation and environment are ideal then you should take a look at the panel itself. . Wrong Measuring Method One thing people ignore is they use a completely wrong way to measure. . [pdf]
