Neutrality Dispute[edit]

The section Benefits of Solar Boats is not neutral at all. It is slanted completely towards solar power. --MorbidEntree (talk) 21:08, 24 May 2016 (UTC)[reply]

Which of the benefits mentioned are not there in solar boats?--Sandith thandasherry (talk) 04:22, 27 May 2016 (UTC)[reply]

I'm not saying that it isn't factual, just that the language used (in my eyes) does not seem to be in a neutral tone. --MorbidEntree - (Talk to me! (っ◕‿◕)っ♥) 04:47, 27 May 2016 (UTC)[reply]

What do you mean? --MorbidEntree - (Talk to me! (っ◕‿◕)っ♥) 06:45, 27 May 2016 (UTC)[reply]

I mean to achieve the necessary neutrality.Sandith thandasherry (talk) 07:44, 29 May 2016 (UTC)[reply]

Factual correctness[edit]

Things just don't add up here. There are two 20KW motors. Assuming they run for six hours every day, their consumption would be 240KWh (20 X 2 X 6). In addition, the boat would have other electrical loads. However, even without the peripheral loads, the panels have to generate 240KWh each day. The article also says that the installed panel capacity is 20KW. Here, assuming that each day offers a humongous 8 hours of clear bright full-strength sunlight, and a supreme efficiency ratio of 90%, the total power generation would be 144KWh. This is about 100KWh short of what's needed. In reality, the efficiency factor would be well below 80%. In reality - again - full sun's power can be harnessed for about 5 1/2 hours a day. This is in line with the Wikipedia article on [Cell Efficiency].

Either the figures are completely off kilter or, there's another power source on board. Whatever the truth, the article appears completely flawed. In addition, the article seems like an advert for the manufacturers. — Preceding unsigned comment added by Tsagar (talk • contribs) 08:56, 17 July 2016 (UTC)[reply]

It is clear that the comment is made without understanding the powering of a vessel that is catamaran, 24 T in displacement. The least the person could have gone through the white paper given in reference. For normal operating conditions, i.e speed of 5.5 knots, the total power needed is 16 kW in total (8 kW x 2 motors). During manoeuvring, this power need increases to about 22 kW (11 kW x 2). Since the two systems, port and starboard, is electrically separated for redundancy, in case of a failure of one system, the boat can operate with one motor. Unlike diesel engines where efficiency drop when engine load is less (50%), electric motors do not have such drop in efficiency. Hence 20 kW motors are provided - one as a means of buffer power needs in case of emergency and two for high water current scenario. So, the power needs is only on an average 20 kW during operation. The boat is designed for running 5.5 to 6 hrs in a day. The rest of the time is for embarking/dis-embarking passengers or break-time (2 hrs) during noon. For running, the energy needs is about 110 kWh. Solar panels on an average produce 4 kWh (per kW) in a day after accounting for efficiency losses (in the location average standard sun is 5.72 in a year). So, on average, energy from panels is 80 kWh. The gap of about 30 kWh is provided by lithium battery bank (50 kWh) that can provide up to 40 kWh. This battery bank is charged overnight from the grid and ready to be used in the morning service. In cloudy and rainy days, the running hours is reduced and grid-charging is done in the extended noon-break. Of course, with higher battery bank size, this limitation can be avoided, but the choice was made based on initial cost of battery. — Preceding unsigned comment added by Sandith thandasherry (talk • contribs) 08:16, 23 August 2016 (UTC)[reply]
