Energy payback section

The section was way out of date and I cannot see how it is relevant so I boldly deleted it. Feel free to undo and update and explain why relevant. It was

The energy payback time (EPBT) of a power generating system is the time required to generate as much energy as is consumed during production and lifetime operation of the system. Due to improving production technologies the payback time has been decreasing constantly since the introduction of PV systems in the energy market.^[1] In 2000 the energy payback time of PV systems was estimated as 8 to 11 years^[2] and in 2006 this was estimated to be 1.5 to 3.5 years for crystalline silicon PV systems^[3] and 1–1.5 years for thin film technologies (S. Europe).^[3] These figures fell to 0.75–3.5 years in 2013, with an average of about 2 years for crystalline silicon PV and CIS systems.^[4]

Another economic measure, closely related to the energy payback time, is the energy returned on energy invested (EROEI) or energy return on investment (EROI),^[5] which is the ratio of electricity generated divided by the energy required to build and maintain the equipment. (This is not the same as the economic return on investment (ROI), which varies according to local energy prices, subsidies available and metering techniques.) With expected lifetimes of 30 years,^[6] the EROEI of PV systems are in the range of 10 to 30, thus generating enough energy over their lifetimes to reproduce themselves many times (6–31 reproductions) depending on what type of material, balance of system (BOS), and the geographic location of the system.^[7]

Wiki Education assignment: Cold War Science

Hello Emilyenguyen - I guess you are working together - unless you can generalise it to include other countries perhaps you could consider moving the text you just added about installation problems to Solar power in the United States as it might fit better there.

Structure of the article

I'd like to bring this article back up to GA, but I've got some trouble getting started. The article covers both CSP and PV. With the current dominance of the latter technology, I wonder how we should weight the two technologies in this article. I was thinking that to limit overlap with photovoltaics, but recognizing that PV is dominant, we should decidate about 2/3 to 3/4 to PV.

I think it would also be good to remove the section on emerging technologies. The section is quite out of date, and recent literature on emerging trends is highly technical, and may fit better into photovoltaics. The development section could mention new technologies in strict summary style. Any objections? Femke (talk) 10:19, 4 September 2022 (UTC)[reply]

Should any of these articles be merged or excerpted?

I wonder whether any of these articles should be merged or excerpted here or with each other:

Concentrated solar power

Solar energy

Solar thermal energy

Solar thermal collector

Solar thermal enhanced oil recovery

Solar water heating

Solar cell

Theory of solar cells

Solar cell efficiency

Thin-film solar cell

Perovskite solar cell

Organic solar cell

Third-generation photovoltaic cell

Multi-junction solar cell

(there are more articles on types of solar cells - see List of types of solar cells)

Photoelectric effect

Photovoltaic effect

Photovoltaics

Intermediate band photovoltaics

Concentrator photovoltaics

Applications of photovoltaics

List of solar-powered products

Growth of photovoltaics

Financial incentives for photovoltaics

Photovoltaic system

Photovoltaic system performance

Soiling (solar energy)

Photovoltaic power station ("solar farm" redirects here. My attempt to rename this to "Solar power plant" was unsuccessful)

Photovoltaic thermal hybrid solar collector

Thermophotovoltaic

Solar panel

Solar module quality assurance (whereas "solar module" itself redirects to solar panel)

Three-phase micro-inverter

Intelligent hybrid inverter

Solar cable

Solar tracker

Grid-connected photovoltaic power system

Utility-scale solar

Rooftop solar power

For example maybe:

Solar micro-inverter and Three-phase micro-inverter and Intelligent hybrid inverter merge to Solar inverter

Solar cable merge to Photovoltaic system

Soiling (solar energy) merge to Photovoltaic system performance

Photovoltaic power station merge to Utility-scale solar

Grid-connected photovoltaic power system (which says little about utility scale) merge to Rooftop solar power

Solar module quality assurance and Smart module and AC module merge to solar panel

Applications of photovoltaics merge with List of solar-powered products (not sure how as one is list and other article)

Financial incentives for photovoltaics merge to Growth of photovoltaics

Intermediate band photovoltaics merge to Photovoltaic effect

I would avoid using excerpts, especially for a high visibility article such as Solar power. Also most of the listed articles are way too detailed for this general article. --Ita140188 (talk) 09:57, 7 September 2022 (UTC)[reply]

There are too many proposals here. I have some ideas of merges / drastic shortenings to reduce the overlap among the top-level articles. I think excerpt can work for high-visibility articles, but not excerpts of leads (which are unstable/poorly cited, and written in a style unsuitable for the body of articles). Will get back later with two proposals. Femke (talk) 17:40, 7 September 2022 (UTC)[reply]

Have proposed the 4 part merges at Talk:Solar_inverter#Merger_proposal and Talk:Solar_panel#Merger_proposal Chidgk1 (talk) 17:22, 16 September 2022 (UTC)[reply]
