The former Liverpool and Stoke player, 32, has been a free agent since leaving Wigan at the end of last season.
"Because we have had a game every three days we haven't had enough training to test his quality precisely," Luzon told BBC London 94.9.
"He has a lot of experience. We will see and take a decision."
Pennant joined the Latics in February on a short-term deal and scored three goals in 13 outings as Wigan were relegated from the Championship.
The former Arsenal, Birmingham, Real Zaragoza and FC Pune City man was offered a new contract but decided to leave the DW Stadium.
Luzon has signed seven players so far this summer and could still strengthen his squad before the transfer window closes on Tuesday.
"We have time and if we have the chance, financially, to bring quality players to the squad, we will do it," he said.
Charlton Athletic head coach Guy Luzon is considering offering a deal to winger Jermaine Pennant, who is currently training with the Addicks.

Thousands of venues had failed to adapt their premises, with a fifth of shops excluding wheelchair users, a survey found.
There are 12 million people in Britain with disabilities, with an estimated spending power of £200bn.
Businesses are "missing a trick" and must do better, ministers said.
Accessibility information providers DisabledGo visited all of the 30,000 venues in person to assess them, in the largest-ever audit of its kind in the UK.
They found a fifth of shops had no wheelchair access, only 15% of restaurants and shops had hearing loops and three quarters of restaurants did not cater for those with visual impairments.
When they asked leading chains directly for more information, only 4% of 105 national retailers responded.

'Going shopping is a nightmare for me'
"Everyone deserves to be able to go Christmas shopping or enjoy a festive meal or drink with their friends or colleagues," said Minister for Disabled People Mark Harper, who commissioned the survey.
"This isn't just about doing what's right. Businesses are missing a trick by not doing more to tap into this market.
"A fifth of the British population has a disability and they and their households have a spending power of over £200bn. Improving accessibility is a no-brainer."
Shadow minister for disabled people Kate Green said the report made for "depressing" reading.
"While businesses work hard to ensure their premises are accessible, some high street names are failing to make the reasonable adjustments they're required to do by law," she said.
"While it's welcome the Department for Work and Pensions have commissioned this report, this Tory-led government has weakened the Equality and Human Rights Commission that helps enforce disability discrimination law.
"Ministers must say what they are going to do to ensure business meets its obligations to disabled people, especially what help they will give small local businesses."
Barry Stevenson, chairman of DisabledGo and a former director of Marks and Spencer, said: "We are pleased that many retailers have invested significantly in improved accessibility in the last 10 years, but the majority are still not doing enough."
"It's entirely unacceptable for disabled people, their family, friends and carers, not to be able to access all high street shops and facilities."
"Disabled people are not asking the earth; just that management do what's reasonable and think more about how they can help disabled customers better.
"And that includes better communication about their accessibility online.
"It doesn't need to cost a fortune to do the right thing and it could be the deciding factor for disabled customers between you and a competitor."
The Equality Act of 2010 obliges organisations to make reasonable adjustments for disabled people.
Ministers previously put a value of £80bn on the spending power of people with disabilities. But this was re-calculated earlier this year to include friends and family of disabled people, not just disabled people themselves, resulting in the larger figure.
Access for disabled people on the High Street in Britain is "shocking", according to a government audit of more than 30,000 shops and restaurants.

The men were found guilty of violating strict Islamic laws in conservative Aceh and will receive 85 lashes each.
The pair, aged 20 and 23, were found in bed together by vigilantes in March. They have not been identified.
Gay sex is not illegal in the rest of Muslim-majority Indonesia and this is its first such conviction. Aceh is the only province where Sharia is in force.
The sentence is due to be carried out next week.
While the judges did not give the maximum punishment of 100 lashes, the sentence is heavier than the 80 lashes asked for by the prosecution.
Public caning sentences have been handed down previously only for gambling and drinking alcohol.
Aceh has become increasingly conservative in recent years. Strict laws against homosexuality were passed in 2014 and came into effect the following year.
Judge Khairil Jamal told the court that the men had been "proven legally and convincingly guilty of committing gay sex", according to the AFP news agency.
When the sentence was being read out, the two men covered their faces with their shirt and hands.
Local officials claim that Sharia law is in line with Aceh's long Islamic tradition. Munawar, an official in charge of overseeing the implementation of the law, says "people want to implement comprehensive Islamic teachings including the enacting of its criminal code".
He also says the Qanun Jinayat - as the Islamic criminal law enacted in Aceh in 2015 is known locally - is an effective deterrent.
The law covers the consumption, production and distribution of alcohol; gambling; adultery; extra-marital sex and homosexual acts.
Punishments include caning and imprisonment, but not stoning.
Rights activists tried last year to repeal some provisions in the Qanun Jinayat, arguing that it was against human rights and Indonesia's national criminal code - but that was rejected by the Supreme Court.
The caning sentence handed down on Wednesday has been condemned by human rights groups and activists.
"I see this as a criminalisation, a step back for Indonesia and violation to human rights," Dede Oetomo, founder of Gaya Nusantara, an organisation advocating LGBT rights said after the verdict.
Ahead of the ruling, Human Rights Watch had called on Indonesia to release the two men, saying that "the verdict will increase fear among LGBT people not only in Aceh but also in many other, especially conservative provinces" in Indonesia.
The men will be caned during a public ceremony on 23 May in the provincial capital of Banda Aceh - where they were found by vigilantes.
The neighbourhood group filmed themselves kicking and beating the pair and the video was shared widely in Indonesia. Rights groups say anti-gay sentiment is growing in the country.
Aceh was granted special rights to introduce its own stricter Islamic laws more than a decade ago.

A Sharia court in Indonesia's Aceh province has sentenced two men to be caned in public for having gay sex.
