TCT RED is an intelligent solar dish that concentrates sunlight and transforms it into heat energy, (hot water) for low heat (<100C) and medium heat (<250C) applications. The hot water can be used for heating homes, buildings, commercial, agricultural operations, food processing, sanitary/domestic hot water and much more.

Oct 01, 2018 . Three standard configurations of PV array consisting of series-parallel (SP), bridge-linked (BL), and total cross-tied (TCT) are studied. Nine PV panels are arranged in 3x3 array. The suitable solar radiation level to start reconfiguring the PV array according to shading pattern is investigated. Partial shading of 1, 2 and 4 panels in 9 are simulated.

STC is used by solar panel manufacturers to test and rate their panels. The value that interests us is the maximum power (P max) or rated power (P r), which is the nominal power of a solar panel when you look to buy one. It could also be called peak power. In a specification sheet, it’s always indicated in a section with STC nominated nearby.

You might see them under the solar panel specifications sheet and wonder what to make out of them. STC and PTC are both test conditions used to rate the performance of a photovoltaic module (PV panel), while NOCT is referred to the PV cell temperature and it’s obtained under prefixed environmental conditions.
Solar manufacturers include this data in the specifications sheet of a PV panel, which they usually report as NOCT or TNOCT. Another factor that influences PV module temperature in working condition is the mounting configuration of the photovoltaic array.
PTC is generally considered as a more realistic measure of PV output because the test conditions better reflect “real-world” solar and climatic conditions, compared to the STC rating. To give you an idea of the PV panel performance under these two different tests, I selected to random tests from The Go Solar California database.
It is not easy to measure the PV module temperature considering all the meteorological variations. So, scientists defined Nominal Operating Cell Temperature (NOCT) to simplify the calculation. NOCT is defined as the cell temperature of an open circuit PV module, under conditions that you can look in the table below.

Passive solar water heater cost vs. benefits. ... Installation and Maintenance. ...
Passive solar can heat water or air (passive solar heating), or move air for ventilating (passive solar cooling). Most commonly, passive solar technology is used for direct and indirect heating of air, water, or thermal mass.
Solar water heaters are an excellent option for sustainability and a good investment in the long run despite the upfront expensive expenses. However, you should know that it has limitations that make it a good choice. For instance, if you live in an area that gets frequent snow, then fully utilizing the solar-type might be difficult.
