Solceller<\/strong><\/p>\n

N\u00e5gonting som k\u00e4nns helt ov\u00e4rderligt p\u00e5 en tripp som denna \u00e4r solceller. Vi kikade runt en hel del men fasades av priset p\u00e5 dessa elf\u00f6rs\u00f6rjare. S\u00f6kande gav dock tillslut resultat d\u00e5 vi hittade billiga solpaneler p\u00e5 Ebay ifr\u00e5n England. Visserligen b\u00f6rjar man fundera d\u00e5 priset p\u00e5 panelerna var h\u00e4lften s\u00e5 dyra \u00e4n som fr\u00e5n de svenska leverant\u00f6rerna. Men i alla fall, vi investerade i tv\u00e5 stycken 100 W solpaneler plus regulator. Om solen \u00e4r stark under 6 timmar om dagen \u00e4r d\u00e5 den teoretiska effekten p\u00e5 solpanelerna 100Ah (200\/12 * 6). Om man t\u00e4nker att ett bilbatteri \u00e4r p\u00e5 ca 75Ah s\u00e5 \u00e4r det ju helt ok. Men teori st\u00e4mmer inte ofta med verklighet. Jag \u00e5terkommer n\u00e4r vi har monterat batterimonitorn.<\/p>\n

S\u00e5 h\u00e4r monterade vi v\u00e5ra:<\/p>\n

\"\"<\/a>Vi valde en enkel v\u00e4g. Vi k\u00f6pte helt enkelt vinkelj\u00e4rn i aluminium (f\u00f6r att det inte ska korrodera) och monterade dessa p\u00e5 kanterna p\u00e5 solpanelerna. P\u00e5 dessa skruvade vi fast noaf\u00e4sten med vingmuttrar s\u00e5 att vi l\u00e4tt ska kunna vrida p\u00e5 panelerna och i v\u00e4rsta fall snabbt montera ner dom i d\u00e5ligt v\u00e4der. P\u00e5 detta vis kunde vi passa b\u00e5da v\u00e5ra 100 W solpaneler p\u00e5 targab\u00e5gen.<\/p>\n

\"\"<\/a>Targab\u00e5gen \u00e4r konstruerad s\u00e5 att solpanelerna ska kunna vridas i cirka 45 grader mot f\u00f6ren och egentligen hur mycket som helst akterut f\u00f6r att maximera soleffekten. Vid d\u00e5ligt v\u00e4der \u00e4r det \u00e4ven m\u00f6jligt att surra fast solpanelerna i r\u00f6ret framf\u00f6r. Detta fungerade utm\u00e4rkt n\u00e4r vi testade i cirka 15 m\/s rak motvind.<\/p>\n

Vindgenerator<\/strong><\/span><\/p>\n

N\u00e5gonting som vi har upplevt mycket av i b\u00f6rjan av resan \u00e4r mulna dagar. D\u00e5 solcellerna producerar v\u00e4ldigt lite str\u00f6m. F\u00f6r oss som haft r\u00e4tt d\u00e5liga batterier var detta v\u00e4ldigt p\u00e5tagligt. F\u00f6r att komplettera solcellerna \u00e4r en vindgenerator ett bra alternativ. V\u00e5ran namnl\u00f6sa Air-x kopia (k\u00f6pt p\u00e5 Ebay) har kanske inte producerat som vi hade hoppats p\u00e5. Med en kapacitet p\u00e5 400 Watt trodde vi givetvis att den skulle vara l\u00f6sningen till alla v\u00e5ra elf\u00f6rs\u00f6jningsdilemman, men icket. Vindgeneratorn har inte genererat mer \u00e4n ca 50 Watt och d\u00e5 i cirka 10-12 m\/s. Det betyder ungef\u00e4r 4 A. F\u00f6r att f\u00f6rsvara generatorn s\u00e5 har den i skrivandets stund bara suttit installerad i ca en vecka s\u00e5 den har fortfarande en hel del tid att bevisa sina goda sidor. Den kanske inte producerar lika mycket som solcellerna men den producerar \u00e4nd\u00e5 f\u00f6r det mesta, \u00e4ven om det bara \u00e4r 1-2 A s\u00e5 k\u00e4nns det tryggt att h\u00f6ra vindgeneratorn surra i vinden. Jag \u00e5terkommer n\u00e4r jag vet mer.<\/span>
